I haven't spent 30 years going to Vegas like some of you, but I have stayed at the following:

Caesars Palace
Venetian
Paris
Harrah's
Las Vegas Club
Bellagio
Tropicana
Rio
Riviera
Flamingo
Green Valley Ranch

I all I want from a room is a comfortable bed, good TV, good temp control, a strong stream in the shower, and decent room service. Much of the rest is unnecessary for my purposes. Most stays have been at Harrah's. A comped room is a great room.
