I'd vote for Port Orleans, either Riverside or French Quarter -- Because of the boats to Downtown Disney. DD is all decorated, and Santa is there, and lots of Christmas events......Since you have to take a bus from any of the mods to the parks, I think the
boat is the one plus for PO--------All of the moderates are nicely decorated - Not as lavishly as the deluxes (the 5 story tree aand gingerbread house at the Grand Floridian is so beautiful!!), but
hopefully you'll have the time to tour the deluxe resorts while you're there..........Christmastime at WDW is extra magical...........
