I think it's much better to do the Post party because like a poster mentioned you get access to the corral first, so you're towards the front of the corral and you then can take your time eating the deserts afterwards. We did the Pre-party and even with slightly rushing to eat, by the time we got to the corral it was already 2/3 full and we were towards the back, still good viewing, but we had a bunch of people in front of us. As a matter of fact, 3 nights later when we wanted to watch the fireworks again (free), we got a spot right behind the corral and was roughly only 20 feet from where we watched with the party package 3 nights earlier.
