We turned up on the Saturday not knowing this was on and as Brits, we knew nothing about it anyway! We didn't have anything to compare it with as far as crowds go, but it certainly didn't seem bad at all. We managed all the rides we wanted, having an early short queue for RnRC, using fastpasses for later. We managed to make a lunch booking for Prime Time on the day no problem. When we went to see the stage, there was no problem seeing what was going on.(Some good cheerleaders at the time). It did seem that folk had come quite a long way for this weekend - we chatted to a couple over coffee! I remember there being a motorcade or something with stars in too! They were filming around and about but we managed to keep away.
