i have a trip coming up to singapore next month....i'm there quite often & i've always stayed at the hilton, singapore....this time i will be staying at a starwood hotel but the only 2 choices there are the sheraton towers or the st. regis....currently i'm booked at the st. regis but am wondering if its worth spending $400-500 extra over the 3 days by staying at the st. regis....any advice from people who have stayed there would be much appreciated....how are the rooms, how good is the location, how do they treat platinum status guests, do they offer upgrades, is it better than the sheraton towers????
