In a post on the Disney Parks Blog, Tom Staggs commented on the MyMagic+ milestone recently reached that all guests can now participate in MyMagic+. He also commented on further enhancements coming to the program. He said that they are currently working on a way for guests to use FastPass+ when park-hopping so that they can make selections at more than one park per day. He also mentioned that they are working on allowing guests to select more FastPass+ options once they use the three they prebook by visiting the kiosks in the park.
Here is the quote from the post:
We’ve heard from a number of guests that they would like the opportunity to add additional FastPass+ entitlements during their visit, in addition to the three they can plan in advance. So, we’re working on providing them with the ability to add and enjoy additional entitlements on the day of their visit. Once they’ve used the three they’ve booked, we’ll enable them to select another at kiosks in the parks. And once they’ve used the fourth, they can select another, and so on. We also heard that other guests liked the fact that with the FastPass+ service they could use FASTPASS when they park hopped. So we’re working on a service enhancement to add that feature to FastPass+ as well.
