No but you can move your next FP+ time closer now that the FP in front of it has been used as long as there is availability. For example we booked the princesses back to back. Rapunzel 9-10 then Cinderella 10-11. Once we use rapunzel FP we can then move Cinderella to a closer time so we don't have to wait until the 10 to see her it might be able to be changed to 9:15 or 9:30
I did this with my FP+ on my trip in August and it worked out great
without a smartphone, how do you to that?
