Hi Sierra!
Walt Disney World offers so many options when it comes to
Theme Park Tickets. Whether you decide to have all of your fun within one park per day, or you're looking to add the Park Hopper option to your tickets, you're sure to have a magical time.
Since budget is your main concern, I would suggest purchasing 3 day Theme Park Tickets with the Water Park Fun & More option added onto the package. With this option, you will be able to visit one park per day. You will also be able to visit Disney's Blizzard Beach or Disney's Typhoon Lagoon on the 3rd day of your vacation. This package also allows you to visit some other amazing Disney attractions, like DisneyQuest (great fun for adults and kids), Disney's Fantasia Gardens Miniature Golf Course and more. Please also keep in mind that you will have to pay for parking once a day at the theme park you visit, so that should be factored into your budget.
I hope that answered your question, Sierra. If you have any more questions before your vacation, please feel free to ask us at any time.
Have a fantastical Disney day!
