Just to come back on the other side.... I buy direct. I only buy direct. Some on here would tell me I am insane. That's fine. For me, it's not a financial decision. it's a who do I trust decision. I trust Disney, and I like doing business with Disney. That's why I decided to buy into DVC. Could I have gotten it cheaper resale? Absolutely. I could also have gotten my car cheaper if I bought it used. I could have gotten my house cheaper. I can get
DCL cruises cheaper maybe via agents or coupons. However, I still go direct to Disney for DCL. It's not a financial decision, but it is MY decision on who I do business with and sometimes I don't mind paying a little more because I am more comfortable that I am getting the product I am paying for. I like working with the DVC agents. They explain everything to me very clearly and walk thorough the process with me. I don't get that in resale. I still know my DVC people who sold me my contracts (both of them) and they still work there. I even see them every now and then. I don't get that with resale. I can call them up on their cell if I have a problem - they don't mind (although I haven't had to).
Also, I did not rent points before I purchased. I don't rent points. I don't play in that market for many of the same reasons. I always bought my vacation packages from disney.com - not even from a TA.
THAT SAID. I DID stay at BLT before I bought there. Stayed there on cash - was lucky to get a room. That was when we decided to invest in DVC. I DID research DVC - had researched it in fact for 5 years before I bought into it.
To the OP - research always pays off. An informed buyer is a smart buyer. You will never go wrong by knowing more.
However, do not feel that you are making a bad choice if you decide to buy direct. I do, and I would never do it any other way. Don't feel that you have to rent points. I didn't, and I still don't. There are a lot of financial people on here that evaluate every purchase to the dollar and cents. There are a lot of resale advocates on here. That's fine - for you - do it the way you want to.
Although I do think it's a smart idea to stay at poly before you invest in it. You can always stay on cash for one trip and spend some time talking to DVC. There is no rush and it shouldn't be a rushed decision.
