no, just at the SSR sales office, and then only for resorts in "active sales."
DVC will sell you a contract at "sold out" resorts like BCV or VWL (assuming they have inventory available - if not, you'd go on a waiting list), but the guides/salespeople are probably compensated more highly for selling AKV, aulani and VGF so you'd have to push to get a so-called "sold out" resort.
there is also a BWV model available for viewing on the boardwalk, but you can't get a presentation there.
i'd also agree that info from a presentation (from salespeople who get paid if you buy and get nothing if you don't) is more likely to be skewed (and sometimes flatly not accurate) than the info you'd get on the DIS.
