Hi Dawn,
My husband loves the Wilderness Lodge! It is his favorite resort and it has my favorite restaurant-Whispering Canyon Cafe:) It is a great place to have a birthday as I have celebrated with my family here a few times.
This resort has rooms which face the main pool but they can be loud if you want your children to go to sleep. All the rooms are great and there is only one bus which services this resort which is located by the entrance to the Disney Vacation Club rooms just outside the general store. To get to the Magic Kingdom, you will take a boat which is at the back of the resort by the pool.
Speaking of pools, the main pool starts in the lobby and literally blows up via a geyser! Plus you can feel like a salmon and swim up stream on one section.
If you should get a rainy day, ask for the scavenger hunt to look for items around the resort which is fun.
Finally, make sure they know you are celebrating a birthday because extra pixie happens with birthdays!
Wishing you a magical vacation!
Beth
