Hello Tammy! I'm glad that you brought your question to planDisney! We want to make sure you can get the most out of your planned Thanksgiving vacation! You're visiting Mickey during a great time of the year!
I think there might be some confusion that I'll try to clear that up so that you can get on with planning a magical visit! When vacationing at the Walt Disney World Resort, Guests may visit one park per day. You cannot visit multiple parks in one day. However, Guests may purchase multiple day tickets as they plan their vacation. After reading your question, I reached out to a friendly Cast Member to confirm that you can purchase multiple day tickets. You are not limited to a one-day ticket purchase.
If you visit the
Walt Disney World Resort admission and tickets page, you will find an option to purchase tickets for multiple days. First, you'll select the number of days you want tickets to visit the parks. At this point, you'll notice that ticket prices are reduced for the more days you plan to visit. You'll then be prompted to select the first day that you want to visit the parks.
Tammy, prior to purchasing your tickets, be sure to check park reservation availability using the
Disney Park Pass System. This system will show you exactly which of the four Disney Parks are available and which have already reached capacity on the days you expect to visit. Good news! I checked availability for the time frame of your visit and I see that all four Disney Parks are available as of writing this answer to your question. Please note that park availability is subject to change. Be sure to check soon and get your tickets while all parks are still available!
