Hi Caryn!
Thanks for your question. I love Fall trips to
Disney, and especially when it's somewhere near Thanksgiving, one of my favorite holidays! :-) Disney
theme park tickets with Park Hopper Option is a great option to choose! Just having the advantage of starting at one theme park, and maybe finishing at another theme park is a cool option, and gives you the best of 2
theme park experiences (or more, if you can make it to the other theme parks in any given day).
To answer your question: You most certainly can add the
Park Hopper Option during your stay, for whichever days are remaining on your base ticket. If you're staying at a Disney Resort, Concierge can assist you with getting this added. You can also at anytime reach out to Guest Services at (407) 566-4985. The Cast Members here are always willing to help their guests make their Disney experience even more magical!
Hope this helps. Have an amazing
Disney vacation!
Terry
