You can book room-only with the AAA discount by calling disney if you're really antsy about requests, but my AAA TA noted ours for us. When I was booking my package through AAA, my TA had me AND the WDTC on the phone at the same time, alternately placing one of us on hold at a time while she relayed information and I made my final resort selection. I wouldn't worry, especially if you have a confirmation from AAA and you feel confident in your TA.
