Was very easy to book direct with Disney and also Dreams Direct as they sometimes have offers. I have been ot Disney for the first two weeks on one occasion, over Christmas and New Year on another occasion and over Christmas on another occasion.
To me December is just magical, I love the shows, especially the carol concert and the decorations are lovely. The weather can be anything, cold one day and then hot another. The holiday fireworks are brilliant as both Epcot and MK have either diffferent or additional fireworks for the whole holiday season.
You'll love December it's great.
