Hi, we have just got back from DLP and did the Princess Pavillion, the queue for thhe tickets opens at half 10, by the Old Mill, we ended up queuing here for roughly 45 mins. The ticket gives you a half hour time slot to return (ours was 3:15 to 3:45). We turned up then and were able to go straight in, however once we got in we ended up queuing for 1hr and 20mins. There were a lot of unhappy people inside having queued for so long to get a ticket and then queuing again when you got in. If you miss your half hour time slot for whatever reason, most of the staff will not let you in (we saw a lot of people being turned away), and you have to have whatever time you are given. Hope this helps
