Sad to hear the Cavalieri is becoming a Ritz. I can understand why though. Was staying there on points when the Pope was selected. Had a room on the executive floor, private elevator club access and double doors looking at the back of the Sistene Chapel. The club room is exquisite.
I might mentiopn a few others where we have had good experiences.
Hilton Amsterdam, great executive rooms with good views of suburban Amsterdam Rooftop Club Lounge is great!
Hilton Park Lane, London after complaining got a great big executive room. The club lounge was very good.
Hilton Charles DeGaul (SP?) Airport has great executive rooms and a very nice club lounge for an airport hotel. People very friendly.
