Rolling seems interesting but really risky and not really practical. I really only see it being beneficial if you came into the park with no plan. Otherwise why would you risk a more desirable FP for the Mine Train or Space Mountain to be able to rapid fire FP for small world or Philharmagic which don't even need FP. I see it working if you don't have a real plan or agenda and just want to be able to see as much as you can without regard for a specific attraction.

When we were there the top tier attractions were not always available later in the day especially at Hollywood Studios. If you wait to make one until later so you can use the rolling system to it's maximum you could end up shutting yourself completely out of getting one altogether for that day. I don't think I'd risk it, but that's just me.

Under the new system can you get fast passes for the same ride more than once?

I'd be curious to see how well the "rolling" FP+ works. knowing from our previous trip, if you wanted Belle, Peter Pan and SDMT, you needed to book them early. And i take it that if you have FP+ from 9AM through 11AM, you can't schedule your 4th FP+ at 901 when you walk through your first attraction?

I really would like to see what people can really get if they do the rolling FP+ with only 1 reservation.

I don't think that Disney should have tiered attractions at some of it's parks. And if you are still only allowed one fast pass for a tier 1 attraction per day, this can make for a miserable visit to that park. The tier 1 attractions are obviously the e-ticket attractions that everyone wants to experience.

It was possible to 'roll' your fastpasses before! You just had to try to make your second one earlier after using your first one! It didn't always happen, but when it did it was fastpass city.
