Hi Lacy! I'm glad you liked the monorail idea and you have some great ones, as well! All of those things would be a lot of fun.
A couple of more ideas I thought of:
1. An anniversary dinner at
Narcoossee's at Disney's Grand Floridian Resort. It's another of our favorites! And, your kids could play in the nearby
Children's Activity Center at the Polynesian Resort while you have some adult time to celebrate ten years!
2. Or, if you want it to be a family celebration, we LOVE the
Hoop-Dee-Doo Musical Revue. This dinner show is so much fun for everyone! It's located at Disney's Fort Wilderness Resort. You could get there by taking a boat from outside the Magic Kingdom as part of your monorail/boat tour!
3.
Speaking of Fort Wilderness, check out all of the fun activities that are offered there! You could make a whole day of fun. There is also a beach area and playground there. We used to go over early for the Hoop-Dee-Doo Musical Revue so our boys could play in the sand and on the playgrounds.
There are really SO many things you can do at Walt Disney World Resort without stepping a foot inside the parks!
I hope some of these sound good to you, and please let me know if you have any other questions!
