No, when they see your wristband, they'll move you over into TommorowLand until the party starts. They close down at about 6, move you to TL and then reopen at 7ish. Although I have to say that last year when we ate at LTT, we got done eating at about 6:40 and Liberty Square was full of people with wristbands. and Frontierland was pretty hopping also. The year before we ate at the same time at LTT and when we got out at 6:45, there was no one around. Wonder what the difference was.
