Hi Maria,
Thank you for visiting us again at the
Disney Parks Moms Panel. A vacation during the fall season sounds exciting. You will be arriving just in time to celebrate the food and music from the world during
Epcot International Food & Wine Festival.
When you purchase
Theme Park Tickets (by themselves, or part of a
Magic Your Way Vacation Package), they are valid for up to 14 days after first use. You also add options such as Park Hopper, which let you visit more than one Theme Park on the same day, or Park Hopper Plus which gives you admissions to the Water Parks or rounds of miniature golf.
Park Hopper Plus gives you the same number of admissions based on the number of Theme Park Ticket days. These are also valid for 14 days after your first Theme Park Ticket visit. In your case, you can still use any remaining admissions after you check out of your hotel.
One last tip: remember you can make
FastPass+ reservations 60 days in advance of your Check-In when you stay at a Disney Resort hotel. Happy planning!
Ricardo.
