Ahhh..now we see an issue. IF you book with a travel agent, you can't talk to Disney about your reservation. Why? It's not your reservation until you check in. AAA owns that reservation. So, they need to make all those arrangements for you. That's common knowledge here.
You aren't going to get vouchers in time...DME needs 10 days to get them printed and out to you. This all should have been done much earlier. Disney/DME isn't doing anything wrong..you just didn't understand the 'rules'...too bad your AAA office didn't explain them to you.
So....have AAA make the DME reservations for you. They can just say that you are being dropped off at the airport, so no flight info is available for your arrival at WDW. Then, when you get to MCO, just head to the DME counter, give them your ID and resort reservation info...they will print you up the vouchers that you need.
You are stressing for no reason. This will all be fine. There has never been any dishonesty involved. Not sure why you think there is/has been.
But please, just have your AAA office make the call to book DME. Then, have the DME counter print up your bus vouchers when you arrive at MCO.
But, in all reality (and honesty!!)..you are not able to use DME if you don't have an active resort reservation. So, if you arrive a day early and stay at the airport, you have to give fake info, or try and tell them there is no flight info. And you have to do the same thing for your departure...give them either fake flight info, or tell them you just have to be at MCO at a particular time.
