I purchased a ticket for a 10pm show, got an email confirming my 10pm show, and printed a ticket that said 10pm. I arrived at the venue only to discover the show was at 1am. This tidbit of information was not displayed anywhere on their website. Additionally, their site lists show and door times seperatly for each event, and this specific event was listed as "Doors/Show: 10pm". Can't really get more specific than that. Because of this I was unable to actually see the people I paid to see, as people in my group were planning on leaving around 3am, which would have left enough time to see an opener or two. Additionally, their advertised "4 floors of sound" was really 2 floors, as "The Studio" was closed for unknown reasons and the balcony is reserved for VIP only. The event I had intended to attend was going to be in the Grand Ballroom, but that was actually occupied by another show until 11pm. The entire ballroom reeked of weed and the floor was stickier than a glue-trap. Seriously disappointed and I wish I could get a refund.
