Bangkok? Depends on location. If you are visiting as a tourist, I like to be on the river. My favourite then is the Oriental. Yes, the product might be a bit old, the service is very good (in the hotel, not necessarily in the restaurants) - most five star hotels in BKK have very good service, but the deciding factor for me is the Oriental Spa - absolutely wonderful service in a stunning building.

If you need to be more in town, I much prefer the Grand Hyatt Erawan. It is on the site of the old Erawan hotel, right next to the Erawan temple, one of the holiest temples in Thailand. You can see temple dancers, people make offerings, all steps from your hotel. Rooms are spacious, service is excellent, and the restaurants food quality and service are some of the best in the city! The Spasso Italian restaurant is amazing. Food is great, and later at night, the place turns into a night club with an excellent band. I also like the large pool deck and fitness centre, and the lobby that feels like a sanctuary after you come in from the busy, hot, sticky street.

Singapore? The Raffles is beautiful, and in a pretty good location. Only disadvantage? lots of tourists running around all hours of the day. The Marriott is a bit too gaudy for my taste with its big pagoda roof. The Hyatt just added a great new restaurant. I don't remember its name but it is a large restaurant with several open kitchens. All kinds of food, all very fresh. Also, great fitness facility.

Sydney? The Ritz Carlton on the park is nice, but not very spectacular. The best view without any doubt from the Park Hyatt. It's right on the harbour front, directly overlooking the Opera House. Ask for a room with a view and a balcony. Nothing like having a room service breakfast with Sydney waking up in front of your eyes! The Observatory is apparently very nice too, but no good views.
