Well... I can only speak from my very limited experience (our first trip was last year!), so take my advice for what it is worth. Last year we went to see Fantasmic on the first night after it reopened from rehab. At first I thought we would get the buffet, to secure a spot. But then we decided against it because we weren't sure if our kids could make it that late (it was the last night of our trip). Instead, we lined up about 1 1/2 hours before the event. We were the first line of "standers" (as opposed to "sitters") and we really found that the time went quickly and the crowds were very friendly. We each left a few times to take kids to the bathroom, etc... and I went to the bake shop near the Winnie the Pooh ride and bought some gigantic cupcakes so we could have our own dessert buffet. It was a lot cheaper and really, I thought that it went pretty smoothly considering it was the first night it had reopened after a long hiatus. We are going again in Nov and while I am tempted by the official dessert buffet option, I think we will just line up early again to save a few bucks.
