Welcome to the Disney Parks Moms Panel, Karen!
You're my kind of traveler - I love split-stays! I also have a lot of experience with them, so I am happy to be helping you today.
Can I also say.... wow! What a way to start your vacation, hidden in the forest of the Sassagoula River in a Treehouse Villa at Disney's Saratoga Springs Resort & Spa. In my opinion, it's one of the most unique resort locations in Walt Disney World®.
When it's time to climb down from the trees and move on to your next magical location, Bell Services will complementarily transfer your luggage to your new resort! However, delivery to your new "home" is not guaranteed until after 3pm, something to keep in mind when planning your day. Also, it's helpful to have all your reservation information handy when you arrive at the Bell Service desk - they'll need your information.
If I switch during a "resort day," I like to keep a large tote bag with me to serve as a day bag. During my last split-stay I delivered my items to Bell Services and then hopped on a bus to
Disney Springs to enjoy lunch and bowling at Splitsville. It's a great way to spend the day if you're not going to a theme park.
I hope this is helpful for you, Karen! Please do not hesitate to reach out to me if you should have any additional questions.
I hope you have a "split" of a stay!
