I just found a piece of paper stuck in a book the other day with a date in April and my confirmation number so I am presuming I booked in April last year. I think once reservations opened up you could pick which night. Last year you had to call. I think the event was 8-12 or 7-12. I can't honestly remember and yes there was chips, cookies, mickey bars, strawberry bars and Mickey icecream sandwiches. Lemonade and water to drink. Character meet & greets and a dance party and games throughout the night. I did not feel it was crowded but we got there right when you could get in and got in the bigger ride lines.
