Hello there, Deborah. Thanks for stopping by
planDisney with your question. December is one of my very favorite times of the year to visit Walt Disney World. Everything is dressed up in its holiday best and so festive and fun. You are going to have a magical time!
With your
park pass reservations, Deborah, you are guaranteed access to that specific Walt Disney World Theme Park all day. No need to worry about not being able to get into that specific theme park. Also, I've been
park hopping since its return, at the start of this year, and I've had no trouble with maxed-out parks at all. Only one day, October 1st which was the kick-off of the 50th celebration did park hopping to Magic Kingdom close for a little bit. I would not be concerned about not being able to park hop during your vacation in mid-December.
With your park hopper tickets, you are able to visit multiple
Walt Disney World Theme Parks in one day. However, in order to "activate" your park hopper feature, you must scan in and enter the theme park with the park pass reservation first before continuing on to other theme parks. You don't have to spend any time at that theme park perse, but you do have to go there and use your ticket to enter. The system can see things like that and if you go to another theme park first, you will have to backtrack to the theme park with the park pass reservation first. If the theme park with the park pass reservation is closed for the night, I'd probably suggest you cancel that specific park pass reservation and change it to the theme park that is still open. Day of park pass reservations are pretty easy to get, so I think you would be able to do some switching around if your flight was severely delayed.
Deborah, I don't think you are going to have any problems enjoying your day once you arrive at Walt Disney World. If you have any other questions before your trip, please feel free to stop back by and
ask me. I'm happy to help.
Have fun and happy hopping!
