DW and I debated between going the traditional MB route, or possibly getting Magic Keepers when we get there for our upcoming trip in August. So far, we're leaning MB's. Our fear with the Magic Keepers is that you need to keep track of them instead of wearing them. While we haven't had the new MB's yet (last trip was Nov. of '16), they are a relatively known quantity. We have taken 5 trips, all using MB's, and have not had any issues with the bands themselves falling off. Magic Band-its are a different story though. We're just afraid that if we have to keep track of "loose" items in the Magic Keepers, one is bound to go missing. We thought about getting a retractable badge reel thing for each Magic Keeper, and mounting it on our backpack. However, that would mean that we would HAVE to take our backpack with us on all rides, etc. We don't keep anything valuable in it. Just snacks, diapers for DD, extra clothes for the kids, etc. Nothing we would be overly upset about being stolen, so we like to leave it in the stroller when we're going on a ride, etc. As much as we like the concept, we can't figure out how to make them practical for us, whereas the Magic Bands just get worn like a watch the whole time.
