Multiple hotels in the same complex/building
 

I'm starting this thread out of curiosity more than anything else because it doesn't have much financial relevance to me (as someone who is not an institutional investor).

I'lll kick things off by providing a few examples I know about, off hand (all in Asia, for better or for worse, but I assume this a global thing).

Conrad // SL Hong Kong (two, identical from the outside, towers in the same complex)
GH .// Ren HK (I think they actually are in a single building, but have separate entrances; they share the pool)
Le Meriden // Hilton Kuala Lumpur (same building and lobby; there's basically an invisible line running down the middle of the lobby)
JW // RC Beijing China Central Place (different sized buildings about 250 meters apart)
Hyatt Place // Hyatt House Shenzhen Airport (from the outside, the two buildings look identical)

Questions/comments:
-More examples are welcome
-Can I assume that most of these places have the same owner (per location)?
-If so, does the benefit of brand diversification offset the cost of dealing with multiple management companies? (I have some guesses on this point, but I'll hold them back until further comments come in)
-the hotel within a hotel concept (e.g. high floors are a sub brand) seems like a different case to me, but how is this better/worse than simply selling high floors as club level?

Are there usually multiple management companies? This phenomenon seems to be more and more common; I assume that one benefit is an economy of scale -- you can have multiple brands appealing to a wider range of customers (to a greater extent than you could with a club floor for example) with some common facilities such as a single central kitchen or functions like sales, maintenance, housekeeping, and back-office. Maybe mundane things too like larger-volume purchasing for items used at all of the brands. It could be the same management company even if it were different brand owners, like a couple of your examples.

My husband is from Montreal and recently two (four?) of these have opened near his parents. We've stayed at the Hilton Garden Inn/Homewood Suites. (There is a Marriott equivalent a block or two away.) The oddest thing about the experience was that they were separate Wi-Fi networks. Why?

I've noticed this a bit in the US too with some Hilton brands. I would definitely guess that these are under the same owner. Perhaps there are some tax, personnel, and/or marketing advantages that we are not given context to.

By CDG there has long been this kind of thing. Nowadays there is also the Hyatt Place and Hyatt House sharing lobby and facilities.

In Mexico City, there's a combined Fairfield/Courtyard....Same building attached to a shopping center. Half the floors for one chain, half for the other, as I recall. They may have shared breakfast facilities. Can't remember about check-in.

I'm not sure, but my guesses are:
1. Hyatt Place and Hyatt House (everywhere these new builds exist)- probably one management company
2. JW Marriott and RC in Beijing - both are Marritoot brands, but I think cooperation is minimal, though there are also some Marriott Executive Apartments in the complex, so economies of scale are probably good
3. Pacific Place HK - I did a little research and it appears that Swire has 20% equity in each of the three hotels (JW, Conrad, Island SL), but each of them are managed very independently

Perhaps because HGI still charges (in policy, if not reality) non HH members for premium Wi-fi? The Homewood Suites / HGI combo in Baltimore has a separate area for Homewood guests to have breakfast, as it's not included for the HGI guests. The Springhill suites /Residence Inn combo in San Diego (one of my favorites) has a combined breakfast for both brands.

All the ones I've stayed in have the little plaque saying something like "operated by XXXX under license from Giant Hotel Chain International" indicating they have the same ownership.

One interesting one is the Marriott Marquis in Doha that used to be a Renaissance, Courtyard, and Marriott Executive Apartments spread across two towers that were then all merged into one hotel - albeit with different stylings in the rooms based on which tower you are assigned.

LM and Westin in Manama. Shared pool/fitness. Restaurants seem to be cross marketed.

Austin has a combo Courtyard and Residence Inn. Columbus OH used to have a combo Marriott/Residence Inn, but not sure if it is still there.

A number of resorts in Las Vegas do this. Resorts World, for example, has three Hilton properties--a Hilton, a Conrad, and a Crockfords. Mandalay Bay has a Four Seasons in one of its towers.

Happens in Macau as well.

The casinos are interesting use cases because I assume the casino operators (e.g. MGM, Wynn, Melco) operate the hotels that are directly above their casinos, and in the case of Mandalay Bay, I think MGM operates whateverr THEHoltel is now called as well. When they bring in other flags (like Four Seasons), I wonder how hands-on they are. Here in Asia, owners often like to insert their noses into operations a lot. For example, I used to do some consulting work directly for the owner of the Westin Shanghai. He had a team of about 15 people that were onsight most of the time overseeing management and coming up with "suggestions" of their own. The Starwood (this was pre Marriott) people didn't seem to appreciate their presence a great deal.:D

In BOM, the Oberoi (the better one) and the Oberoi Towers share a single large complex. They’re completely separate hotels, but they share the conference/banquet facilities.

I sometime stay at the Aloft River North on Clark street in Chicago. It shares valet parking with the Hyatt Place next door on Clark and the Fairfield Inn around the corner on Illinois. The first time I used the exercise room in the basement I was amazed how large the basement was relative to the hotel so I explored. It turns out all three hotels are part of one large building with different elevator bays but are connected at the basement level and on some of the floors. So you can literally enter the Aloft and exit around the corner at the Fairfield. Also one stay the Aloft was having elevator issues so they told you at check in how to cross over and use the Hyatt's elevators. When you look at the building form the outside the hotels look separate but they are just one large building.

2 different hotel chain brands sharing the same pool
 

Hilton Manila and Sheraton Manila share the same swimming pool, but other than that they have separate facilities; individual ballrooms, gyms, club lounges, separate lobby and entrance.

Built as a casino resort building with 390 rooms for Sheraton Manila and 357 rooms for Hilton Manila.

Accor has been having multiple brands on one site or in close proximity to each other for years in France. There are many sites in France with, for example, an Ibis and Novotel in separate buildings next door to each other. Recently I drove past a site with a full house of the three Ibis sub-brands, Ibis, Ibis Budget and Ibis Styles all together, with an even more budget Formula 1 just across the road.

JW Parq Vancouver and Douglas Autograph Collection - two sides of the Parq Vancouver complex - the Douglas often has JW branded towels.

Newly opened Kabukicho Tower near Shinjuku, Tokyo, has the Bellustar Hotel (Pan Pacific chain) and Groove Hotel just underneath it (part of the Park Royal chain)

In downtown Los Angeles, the JW Marriott and Ritz Carlton share a 54-story building. I think the Ritz occupies around 5 stories. There has been talk of adding a second tower to add more rooms to both hotels. I'm fairly sure it's all run by the same management.

I just spent two weeks at that property. Really zero distinction between the HGI and HWS. From the elevator lobby, turn right for the latter, left for the former. Nice place but ugh the traffic. Did not notice any separate wifi but maybe it was.

Springhill Suites and Residence Inn, 410 N. Dearborn St, Chicago

Marriott has done this for a while - one of their newest is a common building for a Fairfield Inn and a TownePlace Suites on Warm Springs Road in Las Vegas. I haven't been in to know if they do a common breakfast area.

Seen a few Courtyard/RI that share the same building in major cities.

Specifically stayed at the Courtyard Central Park before and it shares the same lobby space but with different elevators from the RI. Presumably same management company and targeting long term or family travelers (RI) vs. more business travelers (CY) from a booking standpoint. Amenities and everything else virtually all the same -- I've always picked the CY side purely due to better earnings and when traveling solo I don't need any of the things delivered under the RI brand standards.

I believe Austin has one of these too.

I think Hilton does the same thing as well combining HGI and Homewood Suites in some areas.

I've also stayed at the Hilton Garden Inn Charlotte Uptown which shares a parking facility with the Hampton Inn but nothing else AFAIK (no shared lobby at least during my stay and no other obvious shared amenities albeit it was a brief stay).

The other obvious one that comes to mind is Hyatt Ziva and Hyatt Zilara -- they often go together (e.g., Cancun) with some shared facilities between the two with obviously one being Adult only and the other being Adult + Kid friendly

Makkah
 

I believe the Abraj al-Beyt complex in Makkah, Saudi Arabia has a few hotels inside. For sure they have a Raffles, as I wandered around the lobby for a bit.

The Dorian, Autograph Collection, and the Courtyard Calgary Downtown - same building with the Dorian on top

Springhill Suites and Fairfield Inn in Moab, UT.
