DVC owner at VWL since 2004 and now have added a small contract VGF (enough to stay in a studio every other year). I have never had an issue with getting a reservation but then I can plan at 11 months out and have been mostly successful switching at 7 months if I wanted. I think that, unfortunately, a lot of new owners don't really understand the importance of the 11 month booking window compared to 7 months. I have had to explain to more than one person the difference between the two. I spoke with a new owner who thought he had priority all the time at his home resort and thought that non-owners would be bumped for him. He thought that 11 months was just the earliest you could book. This goes to not only reading the contract but having a guide who explains the system clearly. I also think people get swept away by the "magic" at the sales center and don't really listen and ask questions.
Having said that, I totally concur that maintenance has gone down significantly since we bought 11 years ago. I wonder if the cleaning staff ever bothers to report dripping faucets, stove burners that don't work, badly damaged furniture etc. or they just leave it up to the guest. I haven't experienced the cleanliness issues that some have, but I have had several maintenance problems which required fixing in order to use the villa as it was intended to be used. I have also reported small problems such as burned out light bulbs (something housekeeping could easily report. How do you clean the bathroom when the ceiling fixture is burned out and it is dark?) Last time I had a burned out bulb in the shower, it took several calls over multiple days to get it replaced.
Frankly, I would like to see Disney concentrate on servicing and maintaining the properties they have instead of adding and adding and adding. This would make DVC more exclusive and the resale value under the " right of first refusal" significantly higher. VGF is a small property and I don't think it is sold out, yet here we go with Poly. I have not read positive comments on that property. If they can't sell out VGF, what makes them think that they can sell the Poly for more $$.
