Halfway thru our first weekend stay at the new St Regis. Bottom line...I will stick with the Sheraton Grande Sukhumvit.

Hits:
Very modern design, almost like a W with luxury touches.
Lots and lots of staff - like an Indian hotel but much better trained.
Good personal attention - every staff member seems to know my name.
Resourceful and helpful concierge staff.
Fantastic Elemis spa.
Great view of the racetrack.

Misses:
No Platinum recognition apart from Welcome Amenity.
Pool area has no shade from afternoon sun.
Very small (27 table) restaurant; more kitchen than tables.
Limited, expensive (750 B) breakfast buffet.
Bridge to Skytrain not yet built.

We were staying on an opening weekend promo rate at 7300 B per night. Could have booked the SGS for 6000 B and gotten a much better stay (suite upgrade, free breakfast at a much better buffet). Not a bad stay, but all other things being equal we won't be back.
