(by the way, Robert, I just submitted two videos of that fireworks show to the Youtube channel if you're interested in putting it over there)
The amazing-ness of Epcot combined with Christmas around the world is an experience in itself. On top of that you have all the special food items, merchandise, and entertainment that's only there during that season. Then, just when you think it couldn't get any better, Disney puts on one of the largest daily firework shows I've ever seen and completely blows the pants off of Epcot. The "Peace on Earth" finale is absolutely breathtaking, and I still can't believe that they launch that many fireworks every night of the event.
We specifically plan trips to Orlando just to attend the Food and Wine Festival.
However, I have yet to go to the Christmas Party at MK - that may top them all. :)
My vote, however, goes to Osborne. I appreciate any event that is amazing, yet doesn't cause huge crowds and doesn't require extra admission.
Just walking around the Park with your hot chocolate and cookie with "snow" falling from above it just makes the Magic Kingdom extra extra special.
Even if you choose not to go on any rides ( we didn't have time with all that's going on ) being there is enough.
Then , when you might think it can't get any better, the special Christmas firework display starts. Believe me it's possibly the best display of them all .....and that's saying something.
MVMCP is one event not to be missed.
