My fiance and I are going for our 5th Annual Christmas time trip. We will be there Dec 7-11. I agree that early December is the best time to go. If you have time, make sure you go around to all the parks to see the different Christmas setups they have, Christmas around the world at epcot,Osborne Family spectical of Lights at MGM, etc... If you have the additional $$$ purchase a ticket for Mickey's verry merry Christmas Party. We go every year and it never gets old. Aside from the parks, the major hotels usually have a beautiful Christmas setup and I recommend traveling around and enjoying them.
