..................but then it took another two years before we actually made the decision. You will hear some that say they regret not buying sooner. We don't feel that way at all. Sure, the cost would have been less but cost is only one factor that went into our decision. It wasn't until we decided that we really, really, really, really, etc. like to vacation at WDW that it then made sense to jump into the DVC pool.
When we bought you could visit models of all of the DVC properties located at WDW so we took the tour. We had already driven around to all of the on site resorts. Then two years later we took the tour again and shortly thereafter we made our decision for BCV.
You have already found that some buy sight unseen and others spend a bit more time looking around. Frankly, I am glad we looked things over first.
Good luck with your decision and keep asking questions.
