This is just me...but I think if I could have gotten over the shock, I would have told the sales guy and manager that THEY built that monstrosity called Saratoga Springs, and that you doubt that THEY would have been so ugly in describing the "red headed stepchild" i.e. Saratoga Springs when it was in active sales...and most importantly...since THEY probably didn't denegrate SSR while in active sales...there is no way of you knowing whether or not BLT is a high quality resort or not. Further, since THEY are forced to denegrate one of their own resorts to sale the new product, it only makes sense that the new resort (BLT) must also be inferior because if it were absolutely magnificent...then it would not be necessary for them to denegrate an older property, plus why would Disney choose to go back to selling a high quality product when they were so successful in selling such trash as Saratoga Springs in the past.
Plus...when writing Disney, I would let them know that your buying resale is something that happened in the past and is over. The salesman and manager did not endear you to Disney Vacation Development, and did not entice you to make any future add-on purchases retail rather than resale.
Personally, if Disney didn't charge three prices...I'd consider buying from them...and woe onto them if they try to take my rights away as a resale customer.
Edit: I am not trying to bad mouth Saratoga Springs, I am trying to show how flawed it is for Disney Vacation Development to denegrate a resort developed by Disney Vacation Development to sell a new resort developed by Disney Vacation Development.
