Rosie, of course nothing is set in stone until DLR makes it official by posting it on their calendar (and even then, it's iffy). . . but from what I have read, F! should be running at that time because they will be repaving Main Street early in the year which will make it impossible to run any parades. Therefore, they will be showing F! (possibly nightly) to make up for it.
That's just what I have read over at MiceChat. . .
