I've stayed here 3 times and have LOVED every visit.
This hotel is a gem among Vegas gems. The lobby/registration area is beautiful and the restaurants here are amazing. I'm a big fan of B&B Ristorante and the Grand Lux Cafe, for starters. Staff are very professional and rooms are superb and very spacious.
I also highly recommend signing up for their Grazie program. :D Can't miss out on special offers and whatnot!
