Where to start? Well, I've been there 2/3 of the last 3 years and loved it. I am blessed that my job gives us off a week between xmas and NYE, my sister is a teacher, my dad is retired, and my mom is nearing retirement - so we'll be able to go back! I haven't had time to read the pages, but I'll give my scoop.
- On Christmas day and NYE (especially NYE), find a park in the morning and plan on staying there. Epcot and MK get the most crowded and will most likely be at capacity around 12pm. Remember, this is Floridian's Time Square, and where they go to ring in the New Year. Add that with tons of tourists visiting, and you have extreme crowd levels.
- While on the topic of NYE, go to MK the night before NYE (New Year's Eve, Eve). They do the exact same show as a run-through. On NYE, DHS is a sleeper. It gets packed, but not as packed as Epcot and MK, and they actually put on an amazing show.
- Go Monorail hopping. The luxury hotels along the monorail have some of the best xmas trees and decoration.
- Disney's Beach club resort (I Believe) has an AWESOME Gingerbread house.
- Pack for cold, and warm, and in-between. Of course, check the weather beforehand, but when it comes to the weather down there during xmas time, It could be mild in the day time, or could damp, windy and cloudy. The Florida sun is the source of how warm it will be (as ridiculous as it sounds). If it's going to be cloudy and 60, plan for it to feel like ~50 and be cold. If it's going to be sunny and 60, the sun will keep you warm and it will feel like a true-60 degree day.
- A fun thing to do during the holidays if you're waiting on line (which you will be) is to see how many Mickey-shaped decorations you can find- and who can find the most.
- Something I decided after going in April, is that come Christmas, if there's a park opened until say 2am for EMH, we will relax at the hotel after dinner, maybe nap during the day, then be ready to go the entire night. The park really empties out the later it gets (obviously) so we will definitely take advantage of it!
- The buses will be extremely crowded when the park closes. No use in rushing to the bus stop. Have some patience and remember you're in Disney. This will help everyone.
- Book reservations early. Reservations for restaurants are hard to come by around xmas.
- If you're Italian like me and enjoy your seafood xmas eve, plenty of restaurants offer solid seafood specials. The best Seafood, in my opinion, that I've had so far was at Yacht club. It's a buffet, so you'll feel right at home.
.. That's all for now. I'll try to think of more!
