when I arrived at POP! about four coach loads of people arrived at the same time. The check in desk was huge with space for about 14 ressie staff, but only three were working, it took me well over an hour to get checked in and I was near the front of the queue!
also I was allocated a room inthe 80's section and it took us about 15 - 20 minutes to trundle our way over there, far too far to make use of refillable mugs at the end of a busy park day and too far to just nip out for a coffee in the mornings before getting ready. If you go there get 'preferred' otherwise its just too big a resort to comfortably get round.
I loved ASMo though and was in the Toy Story building, If I went back there I'd definatley pay the extra to become 'preferred' as TS is now.
