To be honest, the system they have means it never seems over crowded. Your time slot gives you 30min window to get in. This means that there are reasonably consistent numbers in the attraction. A tip I found worked. My ticket was for 1.30pm so I had until 2.00pm to get in. I got there around 1.20pm but didn't que. I went to the cafe to get something to eat then went to cue to get in around 1.50pm. Because it was close to the end time of that slot, the que was at least half what it was when I got there. :wink:
