Welcome to planDisney Deborah!
If you plan to visit two theme parks in the same day, you will need to add the
Park Hopper option to your
Theme Park Tickets. You cannot purchase a two-day ticket to visit two parks in one day.
Here are some options. Purchase a one-day ticket and add-on the Park Hopper option. After 2pm you are welcome to hop to a second or even third and fourth theme park. If you prefer, book a two-day ticket without the Park Hopper and visit one park each day if you only want to explore two parks during your vacation.
To get really in the spirit of the theme parks, purchase a two-day ticket and add Park Hopper for both days. You can really squeeze in a lot of magic with that two-day Hopper!
Price out your options and see what works best for your schedule and your budget. I hope you get to see and do it all during your Walt Disney World vacation!
