I'm trying to reserve judgment until the entire program is released, but I'm skeptical. As for the Magic Bands themselves, they're cute but I don't really think I'd like wearing a band the whole time, if for no other reason than the tan line. That sounds petty, but that's the reason I don't wear a watch or a regular bracelet at WDW. Not real keen on my kids wearing them either. I envision at least one "oh my gosh, I've lost my bracelet because I was messing with it" per trip!
If there ends up being a pre-planned Fastpass option as well as the old fashioned pick-it-up-at-the-attraction kind, which will you likely do?
