This will be our third xmas trip to Disney. We were terrified the first time hearing about all the crazy crowds, but I have to say, we never never waited on line! It can be done. The difference between going this time of year and any other is that planning is a must. I got fantastic info here and joined some touring sites which helped a lot. My biggest tips are these (some have been said before):
1) Plan Plan Plan. This is one time of year it is necessary - but like I said, with a little info and planning your family will have a fabulous time.
2) Get to the parks before rope drop. It is amazing the amount we were able to get done in those first 1-2 hours before the real crowds come filing in.
3) We stayed off property. This is the one time of year I was glad I did. It's waayyyy cheaper (for my family of 5, the savings was huge). With the money saved we were able to drive and park at the parks. The busses can be a nightmare this time of year. I would avoid them at all costs.
4) Make advance reservations and make them early in the day for lunch and dinner. We ate 11PM lunches and 5PM dinners.
5) Fast pass, fast pass, fast pass
6) For crazy crowded events like fireworks and Fantasmic look into booking packages. We did the Fireworks dessert package at MK and had an amazing view with no crowding. We also booked Fantasmic dinner packages which allowed us not to wait in the crazy lines.
7)Leave early afternoon. Exit the park as the herds of people are entering. It was amazing to us when we would overhear (more than once) families who obviously just entered the park eating lunch in a restaurant with us casually saying which rides they should go to. We knew they would be waiting for hours on end. We had already been on most everything and like I said, WITH NO WAIT!
8) Check the weather and bring warm clothes! Last year was beautiful but the prior year was freezing. We had our winter coats, scarves, gloves, the works (especially good for waiting for rope drop).
Christmastime is an unbelievable time to go to Disney, but it could easily be miserable. You do need to plan, plan, plan but it is so worthwhile! Enjoy!
