We bought resale and I have talked with member services several times since regarding a couple of upcoming vacations (adding magical express, changing dates/hotel, booking a cash room with member discount, etc) and everyone I have talked to has been friendly and treated me well so I don't think there is any stigma/second class citizen worry. Obviously they know you bought resale because they have to have a way to track if the points are eligible for non
DVC bookings (other than rci exchange) since they no longer allow that on resale contracts.
I wonder if because of forums like disboards it is becoming more common for people to call rather than waiting for the info in the mail and they are starting to enforce not giving out the info? I know our broker and title company when we closed both emailed us info explaining that Disney would mail us all our contract info and once we received it in the mail we could go online or call to book-it was only because of here that I knew we could call to get it-if there are lots of resale buyers calling every day and it is increasing phone wait times significantly I could see Disney putting an end to it (since it never was policy to give it out anyway). Anyway just want to say that once you have all your login info I don't think you have to worry about being treated differently (other than the known resale point restrictions)
