My family (hubby, mom, sis, niece, & me) went in 2005 for Christmas. We we there from Dec 19th to Dec 28th. It was our second time to go and it was an awesome trip. We heard how it would be very crowded that week and all that and decided to go anyway. We did the MVMCP on the last night it was held, again was supposed to be really crowded. But surprisingly we felt that the parks weren't as crowded as we were warned. Some of the best things for us: the dining plan (not worrying about budgeting for meals was relaxing); staying at the Contemporary (a treat to ourselves) and getting back to our room from AK, DHS, or Epcot and getting to watch the fireworks from our room nightly (priceless); my husband being thrilled to have a turkey dinner on Christmas day (a family tradition) at the Wilderness Lodge (buffet style, character meal, and we got our photo taken before dinner); making fun of people all bundled up for 50 - 60 degree weather (no offense intended to those people - up north those temps were like a tropical heat wave to us) and getting to ride splash mtn 3 times in a row (during MVMCP). The weather was mostly sunny and nights were chilly (sweater weather to us). Seeing everything all Christmas-y was so cool. The trees in each park were beautiful. Would we do it again? Absolutely. Would we recommend other try it? With heartfelt excitement!!!!
The only thing that keeps us from another Christmas trip is SWW. DH and DN LOVE Star Wars. Our first family trip fell during SWW and in 2007 we hit it again. This year just DH and I are going and we'll be there for SWW.
