Thanks mrhub and kathys - that is exactly what I thought. MDE still shows our January bands as being active and we also get new ones for our September trip so I will be trying the existing ones to get on the ME!
Jan I have 4 active bands, & 2 more on the way for our trip in May and Nov. All are active, any can be used. You can deactivate any that you wish. I can wear a different band everyday if I want. If you lose one you can mark it lost and if you find it you can reactivate it, all from your MyDisneyExperience page. You shouldn't have to connect anything to your bands, new reservations should automatically link to your band, ours do.
