In my opinion, I think it's great that Disney rents the DVC resorts. All people can't afford a membership, but can afford to rent a villa for even a week and enjoy the experience of staying in a villa, without the costs involved in membership.
In the early days of WDW, long before the DVC was ever conceived, resort prices were at a price point that didn't allow many families who visited Disney to experience the added magic of staying on property. My personal opinion is if you haven't stayed on property, you haven't really visited Disney. I was glad when Disney decided to open the Value Resorts at an affordable price point allowing more people to enjoy the Disney magic.
As for a "Member's Only Resort", As a member, I just don't see the need for or the feasibility of such a resort. What would we gain, except as previously mentioned, higher annual dues?? I'm sure such a resort wouldn't lower our costs in anyway, nor give us more or upgraded benefits, without a very large option package.
I know we all have our ideas as to what should and should not be done, and I respect all opinions stated here. The above is only my thoughs on the subject.
Hope you all have many more Happy Disney Days!!!
