yes it is a nightmare, but it is also worth the trouble.
we always loved to go in the fall and attend the halloween party, but the schools will no longer allow the children to miss school for disney.
we have been at wdw for new years and loved it. the new years eve party at the mk was the best ever. we have been for spring break and had fun but don't really want to do that again. so crowded you could not see your own family when they were right next to you. we have also been there for thanksgiving and had a great time.

the best thing that has happened to my family and wdw is our dvc membership.
we are going to spend our christmas at wdw this year and plan to really enjoy it.

i will let you know
i have gotten too old for the hot weather in the summer, so we hop, skip, and jump around the cooler months. but it has become increasingly difficult to get the reservations without planning way ahead.
