I used the "L" word early on in this thread, and I truly believe that DVC is a luxury. The notion of "pre-paid vaction" also fits into that category. How many people in this country have 30-50 years of "pre-paid vacation"? This term is really a misnomer, since it is not completely pre-paid. If it were, I could just show up without cash or a credit card and be on vacation.
As others have said, I don't think the responses on this thread are meant to be condescending or insulting. I think most of the the comments are in the spirit of sound financial advice. Alot of people visit these thread to learn about DVC, and should be made aware of all of the costs that go into owning DVC.
We bought into this luxury by financing the purchase to the tune of 10.75%. In fact, I made the final payment on our loan about 15 minutes ago! Do I wish I had that interest $$ back -- sure. But, we got 3 trips in 2BR villas over the course of the time we were paying off the loan, and the amount we paid in interest does not come close to what those three trips would have cost in lodging alone. Plus, we still have 46 more years of pre-paid vacation!!!
To the OP, do what you feel comfortable with based on your current financial situation. We had no problem with financing the purchase because we knew we would pay it off in 2 years. As long as you have a plan that you can stick to, you should be fine.
