Hi Chondra!
Thanks for your question and for visiting the Disney Parks Moms Panel!
It is always exciting to be planning the next trip to
Walt Disney World, isn't it??
I have been to Walt Disney World BOTH during February and April school vacations AND during the holidays, and the parks seem to be much busier during the Christmas holiday week! Now, obviously crowds can vary from year to year, but I believe, historically, that Christmas week is THE busiest time of the year in all of Walt Disney World.
That said, it is such a beautiful time of year to visit! The
theme parks and resorts are all decked out for the holidays and
Magic Kingdom celebrates with
Mickey's Very Merry Christmas Party. I, and my girls, delight in seeing it snow on Main Street U.S.A. and we highly recommend this party! Plus, the weather is much more comfortable (for me anyway) in December than in Spring.
I hope this helps and I wish you a Magical trip whenever it may be!!
Chris
