We waited in line for 1 hour and ended up leaving (there was only 20 - 30 people in front of us)because there were only letting in small groups of 10 in at a time every 45 mins. By the time we left, there must have been a line of 100 people. It would take the 100th person 5 hours to get in at the rate they were letting people in. The only reason the line move was because people left the line.
Cons: long, long, lines
