Thank you for the info! According to you what they are doing is going to cause problems because they had the chaperones create and MDE and order the bands. They then intend to have the students create individual MDE for their tickets, but hat hasn't happened yet. I just don't think they understand what they are doing, and the impact it is going to have on the kid's trip. I am not going on the trip, but am meeting DD there after. I thought the best solution was to have what you are describing initially with chaperones in control, but was overruled.
I think that is an accurate assessment, that they don't really understand how the system works.
At this point they have a couple choices, and I understand, since you are not a chaperone on the trip, that it might be tough to communicate this diplomatically! (But they do recognize that you're a Disney "pro", so there is hope!)
They can leave everything as it is, in which case they can either...
1. Have the room chaperones link the tickets to the students they have created profiles for when they ordered their MagicBands. Then they will have to book FP for all of those students. It will be very difficult to get the touring groups on the same page, and just about impossible for them to modify FP or add more after they used the pre-scheduled ones, since the chaperones will have to do it all. Not ideal.
2. Have the kids create their own MDE accounts, and link their tickets. Then at the parks, use their MagicBands to open their room doors, and their ticket cards to enter the parks and fastpass lines. This is actually what we end up doing with our large marching band groups of 150-200, because of the way the rooms are set up for those groups. Not a perfect solution, since the MagicBands are more convenient (and harder to lose!), but definitely doable. The only possible problem I would foresee could be confusion over duplicate names and other info between the profiles the chaperones set up and the ones the kids do. Yes, I'm sure there are multiple Jordan Smiths in the MDE system, but once you end up with duplicate emails with parent chaperones, etc., it could be an issue.
OR you can try to convince them to do the work ahead of time to merge the profiles that the chaperones created with the accounts the students will create and link their tickets to. It will take some time on the phone, but as I have mentioned, I find Disney IT extremely helpful. They realize the system is glitchy, so they seem to have extra patience! They have heard it all, so they can usually solve any issue.
They have to understand that a MagicBand can be linked to only one guest, in one MDE profile. So since they created those profiles to order MagicBands, the students cannot have a DIFFERENT profile/account with their tickets, and still have the MagicBand (which is linked to the chaperone-created profile) work. Nothing is loaded "on" or directly linked to a MagicBand. All they do is access the info in the guest's MDE profile -- in this case, the one the chaperones made.
Hope that makes sense and the kids have a great trip no matter how it shakes out!
