Loyalty programs aside, I'm faced with a choice of the following properties, all have roughly the same rate:

Intercontinental
Westin
Holiday Inn Express Clarke Quay
Holiday Inn (Atrium, Orchard road, etc.)

I left out the Sheraton....I stayed there last time. It's pleasant, but not very central without a subway ride or long walk.

I'll be there basically 3 full days. Location is a bit more important than the hotel itself (which is why the HIE is on this list, although I fully know that IHG properties in Asia are pretty amazing overall).

I was in town two years ago for about 4 days. Did the Orchid garden, some shopping, etc. I like the shopping malls, Chinatown, cheap eats, Clarke Quay, etc. Marina Sands was awesome, but not necessary on this trip.

Any recommends? Thanks.
