What hotel? I stayed at the Kensington Park and loved it. Personality hotels has a bunch of boutiques there. Coach is actually right "off" Union Square and there is a BUNCH of fabulous shopping. Behind the 8-story Macys is a lot more shops with a mall they were building in '05 that has Bloomies.
The Coach is 2-floors. To be honest, that is the first trip I ever took that I didn't buy a new bag.
Have fun!!!
