I love the Rennaissance, great view of planes, but rooms are unfortunately very small, cramped. Their room service ice cream is to die for.
Crowne Plaza has the best rooms! American style rooms, large, big indoor pool, buffet breakfast, etc. Their windows open, giving you fresh air, while the others don't, least of any I know of. It is a very comfortable hotel, but I don't care for some of the arrogant staff. The staff at the Renn. are much nicer. Also, it is a long ride on the Hoppa, they stop at the Posthouse and Novotel, then nonstop back. Can be quite time consuming, especially with a glitch at the Posthouse, got stuck for about a half an hour when some tourbus parked it,

.
Sheraton Skyline was doing renovations last time I was there, over a year ago, but the staff are wonderful and the rooms are good sized. Decent indoor pool and buffet.
I have "visited" the Radisson Edwardian, rooms are nice, but not much of a view, which is important to me. Friendly staff.
I am sad to hear about the Hilton rooms and very sad that they have upped the Hoppa price. UGH
