Hello Jeanne,
Thanks for stopping by planDisney with your question. It sounds like you are getting ready for a truly magical vacation! Hope you are ready to make some incredible memories.
You'll be happy to know you purchased the right ticket to make your vacation plans work. By adding the
Water Park and Sports Option to your
Walt Disney World Tickets you are entitled to a certain number of visits to
Blizzard Beach (when it re-opens),
Typhoon Lagoon, or a number of other fun activities. Your 4 day ticket entitles you to 4 days at a theme park AND 4 added activities, like visiting a water park. These can either be experienced on the same day as you visit a theme park, or on totally separate days to extend your fun!
Currently, you won't need to make a reservation for a water park, but you will need
theme park reservations for each day you plan to visit Magic Kingdom, Disney's Animal Kingdom, Disney's Hollywood Studios, or EPCOT.
Hope this helps. Enjoy planning your magical vacation!
Diane
