Haven't been recently, like in a few years. But when I did it was SO crowded, just wall to wall people, standing room only. We finally went out to the Terrace, and you could hear the band, and enjoy some space there. Our tix at the time were $25 and inc. signature cocktails and I believe beer and wine. The lines for the cocktails were outrageous, recall only braving that line once, and that one drink was not enough! They did have beer stations that were not as crowded though (might have inc wine at that station too- just can't recall). However with our wristbands we were able to tour the hotel and check out all the cool memorabilia posted throughout, even ventured to the pool/cabana area and enjoyed our adult beverages there, and still rejoin the party as we felt like it. It was def. a party atmosphere, with no place to really sit and enjoy the music.
Maybe things have changed, and more recent visitors can give you a better idea what to expect these days. Post a follow up if you go, in case we ever decide to try it again!
