Toby--
I stayed there around Christmas time for a night and its a nice hotel -- the hotel is definitely one of the new hip places to hang out with a pretty flashy weekend scene at the restaurants.
I have no idea about suites but $165 seems a very steep to me -- I'd probably go for the normal room, unlikely you'd get the upgrade to a suite anyway. Its only a cat. 1 hotel so 5K points seems like a much better deal!
Anyway, this hotel is convenient to the airport but not to central Mumbai (the only things around it are other airport 5-stars), so I would recommend if you want to check out this hotel, take advantage of the pickup service and stay for a night the day you get in or right before you leave, and then move into the Oberoi or Taj in central Mumbai for better access to stuff to do. These are more expensive hotels but better for exploring.
The RC is actually on the 2nd floor and open 24 hours!!
The guy who was running the RC is named Rahel and is super-friendly. The room we got was fine, nothing spectacular but in standard Hyatt modern style, with a nice bathrrom if nothing else... I was there about 2 weeks after the hotel opened so I imagine things have settled down since then... RC has a very nice breakfast in the am and alcohol and canapes at night with some cheese and crackers, nuts, and soft drinks all 24 hours!
The hotel has FREE pressing so worth taking advantage of.
Food in the restaurant is good, but expensive by Indian standards, not sure about health club, pool, etc as none of these things were open when we were there.
When are you going? My family is from Mumbai so I can definitely give you lots of suggestions on things to do.
The quick list:
* Walk around south Bombay and see the great colonial architecture.
* Take a trip up to Malabar Hill and look down at Marine Drive (the "Queen's Necklace") at sunset.
* Visit the Crawford market and the area known as Kalbadevi/Bhuleshwar where the famous Chor Bazaar is (Thieves' Market).
* Go to Mumbai CST (Victoria Terminus) station at rush hour and watch the craziness of the mad crowds trying to get on/off the trains.
* Check out Haji Ali Mosque which sticks out into the sea just north of the city, and the famous Mahalaxmi Temple nearby.
* Have a meal or at least a drink at Indigo, a fantastic Indian/Continental restaurant in the streets behind the Taj Hotel.
* Take a boat out to Elephanta Caves.
* Go see a Bollywood movie.
* Visit the beach at Juhu and have Pau Bhaji on the beach.
I could go ON and ON... it's one of my favorite places in the world.
