Hi, Cari! This is a really great question, so thank you so much for bringing it to us.Yes, you are able to select a Tier One FastPass+ enabled attraction as a subsequent FastPass+ choice once you use your initial three. As you know,
Epcot and Disney's Hollywood Studios employ a tier system for FastPass+ selections. Of note, Guests
must use their Tier One option and both of the Tier Two options before they can make another selection from Tier One. Be sure and check out the linked discussion for one tip on how to experience at least two great Tier One choices in one day.
One way to attempt to secure a second Tier One is to schedule your three selections as early as possible. However, in my experience, availability is very low once you get to that point. When I did this a couple of weeks ago, there were a few available for Test Track and I did notice a Soarin' pop up later that afternoon. Are you by chance heading to Epcot a second day during your visit? You could easily experience more Tier One attractions if so. Another great idea would be to
add the Park Hopper option to your park tickets. You could plan one full day at Epcot, with a FastPass+ for Frozen Ever After and ride one other Tier One at park opening. On the day of your second visit, ride another important Tier One attraction at park opening and experience other Epcot favorites before Park Hopping to another park, such as Disney's Hollywood Studios, where you could have three FastPass+ scheduled.
I hope these suggestions give you some ideas on how to FastPass+ your way to a great Disney day, Cari! Please stop by again if you have other questions.
