We liked using them Magic Bands for FPs, though we wished they'd allow for park-hopping. We were also really happy with their utility as door keys and as a quick way to pay for things. That said, lots of people seem to hate them. I chalk it up to the different ways people enjoy the parks. They were flexible enough for us, but not everyone. Having a few pre-set FPs was fine, and we changed several at the last minute (literally while standing in front of the ride) because we decided to do something different. Also, we learned early that the trick to getting the rides and times we wanted was to pick one of the options presented, and then change it after the fact. That said, I don't see it coming to DLR anytime soon.
