Is it 7 months from date of check in? We have a reservation at AK for November, but are thinking of changing to BLT (if possible at 7 months). MIL is going with us and it will be her first Disney visit and we know she would absolutely love being near MK. So, how does it work when I call? Do I automatically give up my AK reservation before being able to book BLT? Or do they check availability and book it and then cancel the first reservation? I don't want to risk losing what we have and ending up with nothing. BTW, it is not peak time - we will be checking in on November 7th for one week. Thanks!
