Hey there, James! Thanks for your question!
If you are in any of the
Walt Disney World theme parks, you can leave that park for any reason during the day and re-enter the
same park when you'd like later in the day - even if later is just a few minutes. Some people like to go back to their
Disney Resorts Collection hotel for a quick nap or a swim, but it might just be that you need to get something from the car. You don't need a
park hopper ticket to go back into the same park.
If I may make a suggestion, James. My mom had COPD, so she always carried oxygen with her when we visited the theme parks. We found that a safer option and a more convenient option would be to bring the extra tank into the theme park with you. If you bring them to one of the
First Aid centers in the theme parks, they can store it safely for you, away from the blazing Florida sunshine, until you need to use it. As of today, James, you do still need a mask to be in the First Aid centers.
I hope you enjoy a pretty amazing visit to Walt Disney World!
Anna
