It's possible the phone CM doesn't know the correct answer. Did you reserve the 2 br. through Disney or are you using points (your own or rented)? If you are using points then you are either booked into a dedicated or a lock off as nicole88s noted. If it's a DVC reservation calling won't matter as you'll get what was booked w/ DVC when the villa was reserved.
If you have a cash reservation I don't know which you'll get, & it's worth while to call Disney and add the type of 2 br. villa you want as a request to your reservation. For what it's worth, if you end up w/ a lock off, when I most recently slept on an AKV hidabed it was pretty comfortable.
