I mean, if one is only looking at overall cost....staying with cash off-site or at a value resort would be the best. That was actually my mindset for years. We stayed value at WDW and off site at
Disneyland. I never considered
DVC until last year because, to me, the cost wasn't worth it. Value/off site was always going to be cheaper.
But obviously if you look at what you get for your money...DVC is better in that respect.
So if you look at what each resort has to offer....SSR might make the most economical sense but that doesn't mean it will have the most value to buyers. It really is such a personal thing when you look at how much value a resort holds.
