Just had a 4-night stay here mid-March, used a TSU to upgrade to a Regency King suite. Suite was on the smaller side, but good enough—a look at the floor plan would suggest that all rooms are quite small. No further upgrades, but it's my understanding that the hotel only has around 12 suites in total (?), so upgrades might be difficult here.
As a Globalist, we had the choice of breakfast in the Regency Club or at the restaurant. Regency Club was small with ~7 tables and 2 couches, and only had a cold spread for breakfast, but you could order eggs/omelets with the super helpful staff. Happy hour was also cold spread only, some dips, fruits, and finger sandwiches. Definitely not dinner substitute for those who care, but the Club was totally empty the few times we visited. Alcohol selection was upper mid-range to premium (think Grey Goose).
We did get pickpocketed literally right outside the gate of the hotel—some guy suddenly came up and grabbed the arm and the other guy took the phone from the opposite pocket. The hotel was helpful, immediately had security come to talk with us and helped notify the police, but I would just say to be careful. Of course, these things can happen literally anywhere anytime.
A note about airport pickup arranged by the hotel as well. I was told apparently they are new and not allowed to enter the terminal, so you have to exit the terminal and look for the driver holding a Hyatt sign outside the terminal (but before you get to the parking lot). Interestingly a very helpful gentleman from Golden Tulip (another hotel) helped us find our driver. $7 per person from airport to hotel, and hotel somehow told us the return was free. It was a strange interaction so I'm not sure if it's courtesy or standard, or if they were already heading that way to pickup newly arriving guests.
Definitely echo the above review that the pool was murky. Gym was nice, but two attendants seem to hover over guests as they workout. Trying to be helpful, I suppose.
As of my visit both "The Kitchen" (Arabic/Mediterranean) and The Oriental were open, and we had a nice dinner at the Oriental and a decent lunch at The Kitchen. Room service also available with an extensive menu as mentioned above, and orders came quickly. Prices are reasonable by North American standards. Spa and salon still under construction.
I mentioned all the potential negatives and things to watch out for, but overall this really was a nice stay IMO. Staff was helpful and knowledgeable in my experience, the design of the public spaces were absolutely gorgeous and the most memorable thing about our stay.
