Hi Deanna!
Thank you for bringing your question to the Disney Parks Moms Panel!
Finding new and unique adventures at Walt Disney World is one of my favorite things! A tip that I always give to friends is to head back to the
Conservation Station first thing in the morning when you visit Animal Kingdom. You can often see the park's veterinarians treating their "patients". A few months ago, a friend texted me a picture. They got to see a HUGE tiger getting his annual check-up. Her girls were thrilled!
I hesitate to link you to this, because it is a couple of years old so some of the information is no longer valid, BUT it has a
ton of great suggestions for "off the beaten path" things to do at Disney. Most of them are still great ideas for your family to try, and I couldn't fit a fraction of them into this one answer, so I would love for you to see them all. Just do a quick search on anything you are interested in to see if it is still something available.
I hope this helps! Please let me know if you have any other questions as you plan for your trip.
