Hi, Danelle!
Yes, you can certainly visit
Disney’s Typhoon Lagoon on the day you arrive at the
Walt Disney World Resort if you’ve purchased the Water Park Fun & More Option for your Park Hopper Tickets or 1-Day Water Park Tickets for your family.
If you’ve added the Water Park Fun & More Option to your tickets, you will be allowed visits to Disney’s Blizzard Beach or Disney’s Typhoon Lagoon water parks, DisneyQuest Indoor Interactive Theme Park, ESPN’s Wide World of Sports Complex, Disney’s Oak Trail Golf Course, or the miniature golf courses throughout your stay. The amount of allotted visits to the water parks and other facilities are based on the length of your park tickets. For example, a 4-Day Theme Park Ticket will come with four Water Park Fun & More visits. That means you can visit the theme parks and a water park (or the other extra options) on the same day, or visit the theme parks exclusively on certain days and a combination of the water parks, golf courses, etc. on other days.
I hope this information helps, Danelle. Please let me know if you have any other questions as you continue to plan your pixie-dusted Walt Disney World visit!
Wishing you magic,
Courtney
