I went with my 2 sons last night. This was my first time and I would guess the weather held some back from attending. It was a decent crowd but definitely not packed.
We had hung out at the waterpark most of the day. The rest of the waterpark closed at 8pm. My boys decided they wanted to watch the movie instead of dry rides. We walked over to the wavepool about 8ish. They made an announcement to line up on left side of pool if we wanted a raft. They provided 2 park hosts walking around with microphones asking trivia such as "What is your favorite part of the movie? and "What is the snowman's name?" It was just for fun, no prizes or anything. Then, there was LOTS of singing into the mike by the kids. As to be expected, lots of "Let it Go!" was sung lol! Pool was still closed off at this time.
I didn't have a watch but probably around 9ish (maybe a little before), they let us get the floats and enter a roped over section of pool. They let people in the pool in small groups and this seemed to take awhile. It was very organized. We were one of the first groups in and it seemed like people kept coming in. Not sure if they ever ran out of floats.
Many people around us ditched their floats and just swam and splashed. Not sure if they still allow that in high capacity. I had heard once tubes ran out, it was the waiting game until someone got out. We never got out so I can't confirm:)
Movie didn't start until around 9:40. They played some trivia on the screens and promos for upcoming events. My 3 year old wasn't too impressed. My 7 year old wants to now attend EVERY advertised event haha!
It was fun and we would do it again. I might not go right at 8pm though. It was a long wait, but it was a nice evening. Packed capacity crowds (and not being near front of tube line) might have changed my tune though.
My kids want to go back Friday for Toy Story!
