We knew we loved the Epcot resort area - we'd been staying in it since we "discovered" it staying there for a conference almost 20 years ago. We go to WDW fairly often and we always stay deluxe, so we knew we wanted to buy
DVC. We had never stayed at a DVC resort, but because of location alone, we knew we wanted either BCV or BWV. (We had stayed in both BC and BW and liked them both.)
We ended up buying AKV first... We'd never stayed there, but we love to eat at Jiko, we love the theming, and our DS turns out to be a huge animal fan. We are also big fans of Club level, so the fact that AKV had that as an option (even a hard to get option) was a plus. We're really looking forward to those Savannah View rooms, and we will probably try for the occasional Concierge room once DS is a little older and not so totally focused on animals.
We then almost immediately bought BWV resale. So, yes, in a way we bought two contracts site unseen, but we'd been considering DVC for more than a year before we took the double plunge. We have seriously thought about adding on at BLT, but it just doesn't make sense for us this year. We got developer points when we bought AKV and our BWV contract was fully loaded with current and banked points, so we have more points than we can really use this year. More than half of this year's points will end up banked into next year, so we probably shouldn't buy any more points until late next year.
We are almost certainly going to buy Ko Olina points sight unseen, as well. If it ends up not getting built for some reason, we'll probably pick up a different Hawaiian timeshare. We love Hawaii, and we love that with DVC we would be able to use our points easily at WDW if we decide that we don't want to go to Hawaii some third year. (Our current plan is to get enough points for a two bedroom villa, ocean view, for a week every three years in whatever season we decide most appeals to us.)
I'm not the type of person who generally makes big decisions quickly or emotionally, and we thought about buying DVC for more than a year before we bought. We knew we liked the resorts we bought in, even if we hadn't rented points to stay in them. We also didn't just buy them for the look and feel of the rooms; we bought AKV for the animals and we bought BWV for the location. We aren't buying BLT unseen, but we're hoping to at least tour a model while we're there. I'm really tempted by the location, but not the decor( at least in pictures).
