We are buying because when we stayed at Pop last month (first FAMILY trip to Disney, DH and I have both been there before, years ago, but without each other), we vowed to stay Deluxe from now on, and in a better location. We decided that it would be either on the monorail line or in the Epcot area, either at BC or BW. Then we saw how much it costs. Then we also decided that the Epcot area is better for us than the monorail line because it is centrally located AND walking distance to 2 parks we love. To stay at BC or BW in the summer in a regular room for 10 nights (the amount of time we decided our trips would be) would be close to $4,000.
So, we started loooking into DVC. We decided that we would be going to WDW every other year anyway, and as I found out more and more info, we decided it was for us. We feel that we would regret it a great deal if we do not jump in now and lock in these prices. Our kids are only 1 and 3 so we have plenty of family vacations to look forward to with them, plenty of years for them to enjoy Disney in different stages of childhood.
For our vacation plans, this does save us money. Being able to have a one-bedroom at BWV every other year...priceless and something we never expected to afford until we discovered DVC! We decided on BWV for our home resort since we want to stay there every time!
