Follow up question (if I may): Say your fastpass for Space was 2:00pm to 3:00pm and you went on at 2:05pm and were done with the ride at 2:20pm. Let's also say your next fastpass was 3:00pm to 4:00pm for Buzz. Could you go to a kiosk and change the Buzz FP to say 2:30pm to 3:30pm if the time was available?
