Just wanted to throw in my 2 cents about the kiosks. We were at MK yesterday, and although most sites showed a crowd level of 5, it seemed way busier than that, like a 7 IMO, possibly because of the rain on Friday and Saturday, and cheerleaders finishing their comp at WWoS at some point on Sunday.
We had 3 fastpasses scheduled ahead of time, and once I heard about the 4th FP I moved all 3 fastpasses as early as possible. This is key. The minute you finish your last FP, immediately go to a kiosk and book the next earliest FP for something you can tolerate riding. Continue in this fashion. In between waits for FP, ride the non-demand rides (we did Carousel of Progress - I think this was my first time in 10 years!, Peoplemover - turned out to be on of my DS9 faves, lol, character meets, Dumbo, and Barnstormer - all with no fastpass and waits of between 0-30 min) In total, on a fairly busy day, we were able to ride Splash Mtn, BTMR, Speedway, Dumbo x2, Small World, Barnstormer, Peoplemover, Carousel of Progress, Philharmagic, 4 character meets at Pete's Silly Side show, Snow White, and Aurora. We got to the park later than we wanted (10:30am) and also took a break back at the hotel from 3:30-6:30. We returned for the parade and fireworks.
We saw LOTS of people waiting in Standby lines, and while the waits for a kiosk were about 5-10 minutes, we felt it was way better waiting in the kiosk line, getting the next available fastpass for a ride, and walking right on into the FP line. The kiosk lines look long, but were much more bearable than waiting forever for a ride. There were cast members manning each kiosk to help make things go faster, so I can't imagine what would happen if they took those cast members away. Even so, we experienced a glitch at our 4th FP and in general I find the MDE glitchy - as the kiosk eventually just 'refreshed' and then our info was magically there the 2nd time.
So overall, my first impression of FP+ is that it's not as bad as I expected. What it means is you can't plan, you might need to throw that touring plan out the window now, since the availability of FP4, 5, 6, etc. will determine your next ride, but we were ok with that. Book the headliners as your top 3, and hopefully you'll get on the others at some point. I am the type that usually travels with a touring plan, but this was a nice balance between my go-go-go way of taking on the parks and my DH go-with-the-flow attitude. He felt it was a great day. We'll see how it goes tomorrow at DHS
