Although you don't get anything with AAA (CAA for us) anymore, we still book through them as our TA there knows a lot about Disney (WDW, DL,
DCL, Aulani, etc.) and handles everything for us from booking DCL, transfers, hotels, extra tours (in Europe), flights (unless we're using points), and insurance. She also reminds me of dates such as PIF, booking windows, etc. If there's any issues or questions, we just call her. While an OBC would be nice, handling all of my booking details (I just leave with her what I want and she sends us the info later) and knowing that she and the agency have my back if I have problems is worth more to me. And the office is just a few minutes away from us.
