I stayed in the W Times Square last week for our anniversary. For 20k spg maybe wasn't the best redemption, but at least now my wife can't say that I always talk about the trips we are "going" to take and we never actually go anywhere haha.
The hotel was really nice. They sent a bottle of champagne up to the room while we were out. It wasn't kosher, and they didn't have a kosher alternative when I asked, but it was still nice. We got a standard room on the 48th floor. It's in a great location and we had a great time, but next time I think I'm going to go for the Andaz.
