Of the hotels you have listed, the best is the Mandarin Oriental IMO. But it sounds as though that is room only. My partner and I stayed on a club floor at the Oriental and were upgraded to Club Harbour Suite which was fantastic. The lounge is very nice and does a great breakfast (including champagne if you so desire) and early evening drinks and canapes.

The Pan Pacific is very close to The Oriental...stayed in a Club Floor room there as well. The room was OK but we really disliked the lounge. Evening snacks were dull and boring and the lounge was ugly. Would not go back.

The Fairmont has a great location on top of the MRT interchange. I have not stayed there, but from what I have read if you book a room in the newly renovated tower (I'm not sure if it's North or South) you will be happy with your hotel choice. Internet is free for FPC members...free to join.

A Conrad Club room for $250 is a good deal to me. I assume it's the January Sale rate? It's considered a very good SIN property. I would not stay at the Hilton.

The Four Seasons has (or at least did when I was there last fall) have attractive weekend rates. $318SGD including breakfast. It may not be the best property in the chain, but it's still a FS and that will always beat a Hilton, Sheraton etc to me. I like the FS location just off Orchard road, close to the MRT, and very close to the new ION Orchard Mall. It's connected to the Hilton if you want to stay in the AC on your walk to Orchard Rd.

When you and your husband save up your next 240,000 Aeroplan miles...go to Thailand.
