Greetings Jen and welcome to the Disney Parks Moms Panel!
I am so happy to hEAR that you are planning on going under the sea at the Seas with Nemo and Friends pavilion at Epcot. Booking the
Aqua Tour is actually in my bucket list and many friends who have done it say it was one of the most amazing experiences they have had a the Walt Disney World Resort.
Jen, park admission tickets are not required and not included when you book this tour. For reservations you need to call (407) 939-8687 and on the date of your visit you will have to check in 15 minutes prior to your tour outside the Epcot main entrance near the Guest Relations window to the far right. Bring a swimsuit, but do not worry about snorkeling equipment because everything will be provided to you. If you need to cancel this experience for any reason, do so at least 2 days in advance otherwise you will forfeit the price you paid. In case you want to spend the day at Epcot on the same date of your tour, you will need to purchase separate theme park admission tickets. Again, these are not included with the price of Aqua Tour.
I hope this helps you while planning, Jen! Please come visit us again if you have more questions.
Best magical wishes,
Thiana
