I'm rating the gym fitness center only. The gym is AMAZING!! The best hotel gym in Las Vegas. The cardio room is huge and clean. The weight room is well stocked with everything you need for an awesome workout. Equipment is Clean and in good working condition.
I really recommend visiting the "older" fitness room, which is in the Venetian. The Palazzo has a smaller fitness room which Isn't bad, but can't compare to Venetian's gym. I had such a great workout. :)
