There are very few villas at VGC. Depending on how much later you decide you want to switch, there may not be any one bedroom villas left. If it's at the 7 month deadline or later, your chances are slim to none. Changes in rented
DVC reservations are not as simple as changing a hotel reservation. In order to change from a studio to a 1 bedroom, the member you rented from would have to have enough points to cover the upgrade (roughly double the original amount), and would have to be willing to sell them to you (they may have planned to use them for their own vacation). if they don't, AND you can find another member to work with, AND there's still availability, the original member would have to cancel your original reservation for the studio, and make a shorter reservation, however many days worth of a 1 bedroom villa you could get for the original amount of points. Then the second owner would have to make you a second reservation, starting on the checkout day of the first reservation, to cover the rest of your trip. The owners would have to link their reservations so you didn't have to move to a different villa mid-trip. And you'd have to hope and pray that someone else didn't grab the last remaining 1 bedroom villa while all these transactions are taking place - that kind of thing happens all the time - leaving you with no reservation at all. Simply put, it would be a mess. If you are thinking of attempting this, be sure to discuss it with the member up front, before any money changes hands, to make sure they're on board with it. Many members who rent have a no changes, no cancellations policy. Seriously, if you really want a 1 bedroom villa, that's what you should rent.
