We stayed at the Hilton in May 2002, the room was nice and clean. There was 4 of us, 2 adults 2 kids, we had enough room. The hotel pool was nice, you can't beat the location.
If you want extra room, I'd go for the Embassy Suites. If you want some Hilton points, stay at the Hilton. If you are a Hilton Diamond member, you might be able to stay on the 10th floor and get the breakfast in the a.m. and the hors devores and cocktails in the afternoon.
Have fun!
