Hi Sheela!
I'm so happy to hear that you are making your
FastPass+ reservations as soon as possible because it will allow you to make reservations for many of the attractions and entertainment experiences on your "must-do" list!
Since you have added the Park Hopper Option to your
theme park tickets, you will be able to enjoy multiple theme parks on each day of your trip. This means that you can spend your morning enjoying Main Street, U.S.A. in
Magic Kingdom and end your day exploring the countries of
Epcot's World Showcase. When you are making FastPass+ reservations, you can make three advanced reservations for each day of your trip and those three reservations must be in the same theme park. Once you use those three reservations, you can make additional FastPass+ reservations, one at a time, and those reservations can be at any of the four theme parks, allowing you to utilize the park hopper option on your tickets.
I recommend that you make a list of "must-do" attractions and entertainment for each day of your vacation itinerary and use that list to determine the FastPass+ reservations that you want for each day. In general, if you make your reservations in the morning, you will have more opportunities to make additional reservations throughout the rest of day, but there may be some days where you want to use your FastPass+ reservations to enjoy "must-do's" in the evening. Overall, the FastPass+ System is flexible enough to accommodate your itinerary however your plan it!
Let us know if you have any more questions as you continue planning your trip. T-T-F-N, ta ta for now!
