Thanks holula, Tammy and Jeff (hope I didn't miss anyone) -- we will definitely plan to be there well before the park opens on Christmas Eve and Christmas Day.
Back to the issue of Early or Late Dinner: Based on everyone's great advice I'm still conflicted about whether we should do the early seating or the late seating with DD (8) and DS (6). A case can be made either way....and perhaps for us it will come down to whether there are other Dis folks with kids at the late seating.
Is anyone else with preteens doing the late seating? (I didn't see any discussions re who is going to the late seating, but could've missed it.) I think I might be bummed to miss out being in the same seating area as the large group with and w/o kids that's already forming for the early seating. I'm glad we have early seating so that we have the option to go either way, but we're sort of leaning towards late seating if we wont' be there by ourselves.
