Just got back from Disney World where they have updated the Fastpass plus system again. I love the new MagicBands, but the FP+ system needs a bit of work. I've read a lot of reviews and most are negative. You can only get 3 FP's per day and they have to be in the same park, so if you have park hopper tickets, you can only get FP's in one of them. Plus a couple of the parks have a tiered system so it won't let you Fastpass all major rides.
I love Disney, but I'm thinking this wasn't the best idea. I guess we will just go back to "old school" and learn to stand on lines again. :-)
