Hi Lia!
Thanks for coming back to planDisney and I'm excited to help you again as you plan for your next trip!
Standard
theme park tickets will allow you to visit one theme park on each ticketed day of your vacation. The Park Hopper Option is a fantastic addition to your tickets because it will allow you to hop to additional theme parks after 2:00 p.m. throughout your trip. While you can upgrade your theme park tickets to add the Park Hopper Option, unfortunately, it can't be added to only one day of your ticket. So if you would like to add the Park Hopper Option, you'll need to add it to your entire ticket, which will allow you to enjoy multiple theme parks on all four of your theme park days.
My family's upcoming trip to Walt Disney World Resort is just a quick visit, so we've chosen to visit one theme park each day. This will allow us to maximize the time we spend enjoying each of the parks and minimize the time spent traveling between parks. Plus, each of the theme parks has so many attractions and entertainment experiences to offer that you're sure to have a full day of magic every day of your vacation, with or without the Park Hopper Option!
Lia, feel free to come back to see us if we can help you again as you continue planning your vacation. T-T-F-N, ta ta for now!
