1am on a Saturday night with about 20 people in front of us in the general admission line, it took us an hour to get upstairs! Not sure what the criteria was to get in the VIP lane that was moving about 100x faster than our stationary line, but after 45 minutes of standing in a hot crowded hallway, I was ready to pledge my first born child...
Fortunately, that was the only negative part of the night (aside from price of the drinks and size if the crowd, which are both expected). The music was very diverse and the DJ really played to the crowd present. The view was amazing!
Overall the VIP line was irritating while we had to wait, but it was a nice spot once we got inside. I would definitely go back for tables or VIP access, but as a couple just trying to have some fun, not my first (or second or third) choice.
