That's a shame. We've been on two separate trips (testing October 2013, and roll out April 2014) and had no problems. I actual don't have a problem with the bands and find them convenient...as long as you don't take them off during your drawing class and accidentally leave it in the art room
.
My only gripes is that I am NOT a fan of the 'no standby line.' Magic Bands is a great help/aid but you should also be allowed to spontaneously wait in line if you choose.
Also, I wish they had reminded us or made the whole 'pin' bit a more prominent part of the instructions since all 3 of us adults bypassed the fact we needed pin numbers. We had pins in October and completely forgot until we arrived April. One person in our family didn't go in October so got a different pin number. We thought that was for ALL of our bands, turned out it wasn't and caused some issues when we went to eat. We got it fixed quickly but that could have used a little more explanation. Other than that I think they work.
It's just that...all the money they spend on that system could have been used to build cool rides to make people want to visit.
