I didnt care so much about end date but had an upper limit for what I'd pay for one of those resorts, and I'm even wondering why I didn't just buy a ton of SSR points to use for 1BR at 7 months since I've recently decided that I want the space of a 1BR over a studio. But then again that is how you get sucked into
DVC and don't actually save money, because as others have said, you end up going more often, often staying in bigger/nicer than you would've paid for anyway, and then spending more because it becomes very circular reasoning. (Like we really could have gone to WDW for a week be spent less than we did for Ks birthday party, because our room and tickets are already "paid for."
