Have they improved on Fast Pass? We visited Disney 3 years ago.
You were only able to get fast pass for one ride at a time and
sometimes they would run out of them for the day.
Sounds like the same FastPass system that is still in place.
We went during a non-crowded time and used this system very effectively but I can see during a crowded time, if they run out of FASTPASS tickets, it could make your trip a headache.
Wish I had better news...
NOTE: Once the appointment time on your FP ticket begins to countdown, you can get another one even though you didn't use the 1st one yet. We always went to secure our next one before using the previous one so the time would begin counting down while we were on the ride.
