Hello Hillary! You are getting so close to your vacation to The Most Magical Place on Earth! Hopefully you've got your countdown to Disney started! I love that you continue to plan in order to get the most out of your upcoming visit!
The short answer is yes, it is absolutely possible to visit two Disney Parks in one-day! In fact, if you plan on doing so, I recommend that you consider purchasing a one-day
Park Hopper Ticket! This ticket will allow you to visit two parks in one-day and save you some money by doing so! For ambitious park-goers, this is a great option!
However, I want to caution that you take a few thoughts into consideration before deciding to visit two parks in one-day. First, make sure that you are leaving yourself enough time to enjoy all aspects of both parks. You don't want to feel forced to leave one of the parks if you really haven't had a chance to experience all of your "must do" attractions. Second, if you're traveling with young children, keep in mind that traversing just one park can be quite the task! Asking them to do two in one-day can be physically demanding on them (and some adults too). Also, be sure to keep in mind travel time to get from park-to-park. This will most likely involve a transportation transfer and can result in losing time in your day. Finally, if you were thinking about starting your day in
Disney's Hollywood Studios in hopes of experiencing
Star Wars: Rise of the Resistance, keep in mind that you are assigned a Boarding Group and time to report to experience the attraction. That Boarding Group assignment could come at a time when you were hoping to be in another park.
Hillary, you are doing a great job by continuing to plan even as your vacation draws closer! I hope that this information has helped you to make some decisions about how to best experience the Disney Parks!
Hakuna Matata! Jonathan G.
