Hello, hello there, Edna! You're as welcome as can be here at
planDisney. Thanks a bunch for bringing us your question!
Let's get down to the nitty-gritty. Basically,
3-Day Theme Park Tickets with the Park Hopper Plus Option are valid for admission to all four
Walt Disney World Resort Theme Parks on any three consecutive or non-consecutive days during a six-day period, as well as three visits to a Water Park during the same date range. So, in your particular case, your tickets are valid from May 15, 2025 to May 20, 2025. That being said, I'm happy to report that you can absolutely visit a Water Park on May 18!
If you wanted to take full advantage of your Ticket type, you could also visit a Water Park in the morning before heading to the Theme Parks or in the early afternoon for a quick dip in the pool or a relaxing swim in the lazy river! I have done this before, and it's one of my favorite ways to beat the midday heat. Since your ticket includes three water park days, you could do this on day one, day three, and then finally end your magical vacation with a splash on day four.
Edna, depending on how flexible your travel dates are, you could also consider extending your vacation until May 20. This way, you'll be able to visit the Theme Parks on May 15, 16, and 17, and the Water Parks on May 18, 19, and 20! Talk about an absolutely magical trip. Either way, I know that you're going to have an absolutely enchanting time next month. If you have any other questions at all, please don't hesitate to reach back out to us so we can assist you further! Have a magical day!
Warm hugs,
Ana Paula
