Yes, I should have clarified that. I submitted my request at 12 months to "get in line," but I knew 11 months would be the earliest I could get a reservation. It took a couple months *after that* before something became available. It was hard to wait, but I did get my first choice.
And to the previous poster, yes, it seems clear to me that Disney IT is the place to resolve my problem with My Magic Experience. The trouble is--good luck getting to the right person. I've been on hold several times for ages, transferred to different people, I've been *promised* they would get it fixed, etc., etc., and NO RESULTS. And part of the problem is that the moment any Disney CM finds out it is DVC, they want to hang up on me and send me to DVC because they assume it is a DVC issue. Then DVC won't talk to me because I'm not a Member. David's says they can't do anything. So I just go around and around, wasting time and getting nowhere.
The DVC owner needs to call and add the missing child to the reservation. They simply need to call member services. Easy peasey. I have only rented directly from DVC owners, and this is what they did anytime there was a mistake with the reservation (kids ages were wrong, etc.). Then look for the update in
MDE.
OK...lemme ask, when you look at the reservation outside of MDE (perhaps email confirmation from David's...owners send this to me), is it correct? Just incorrect at MDE? If it is incorrect at everywhere, it is a problem with the reservation, and you should pressure David's to fix it (which means they need to contact the DVC owner to make the call, as noted above). Not a big deal.
If it is correct when you look at the reservation (outside of MDE), but wrong at MDE, then call any 407 number, say 'My Disney Experience' for the issue, and it will transfer you directly to IT. We had a DVC/MDE issue, where my DVC reservations had a dulplicate of my 3yo, one that didn't have tickets/FP+ associated...which meant that the magic bands wouldn't work at the parks, just at the resort. The IT guy was super helpful, asked that I change the duplicate identity to something obvious (added 'NOT' in front of the identical name), and he conferenced in DVC IT (separate entity from normal Disney IT), and fixed it while I was on hold. Took about 30 minutes total from initial dialing to hanging up. I was satisfied.
VERY important, call during normal business hours as the DVC employees don't have the same hours as the other DVC CMs. They are 7 days a week, but I don't think they hold evening hours on the weekends. The initial IT guy was worried that they might have gone home for the day when I called on Sunday. I was pleased that he (IT guy) escalated the call to DVC, because they never would have worked with me...can only fix issues directly from the DVC owner, and will ask for membership #/etc. if you try to call.
Good luck. DEFINITELY fix this now, not having FP+ is a big deal. Don'tgive up!
