I own 150 points at VWL and in 2 years have used it twice. We went to HHI last year and have also stayed one night at OKW. This May we'll try BCV for 3 nights; Thanksgiving week we'll be back to VWL. I'd like to eventually try all the DVC resorts, just for kicks.
As many here would have guessed, you can put me in the hard core VWL column.
We have yet to stay at any other DVC Resorts, other than our home resorts (VWL & VB). Of course, I have stayed at a variety of non DVC Resorts using points. I would expect to branch out at some point in the future.
