I guess I'm thinking of an annual vacation. But still, if you bought 50 points, 150 points every three years you're probably only looking at a studio for 4 or 5 days.
What's already been said.
A lot of DVC owners have multiple favorite resorts. But don't need 250 points at all resorts. We started with only 75 BLT points think it would be an every other year or every 3rd year stay. Then we stayed and loved it. So we've added on there.
When the Poly is built I could see wanting 50-75 points there for 2-3 nights here and there with BLT being our main stay.
Points are poitns at 7 months, so many just want the advanced booking window for a few nights at prime times periodically.
Do a lot of people do split stays. I've never done that before but have to for an upcoming trip because they were booked. Is it easy to transfer? Do they move your bags for you?
We only ever do split stays I can't bring myself to one experience one resort in a holiday.
Our preference is to stay at one resort for the whole trip, we like to settle in. But if you want to do a split stay, Disney makes it quite easy. You can just take your bags to Bell Services and they will transfer them to the new resort. But you won't see your bags again until late afternoon, so be sure to pull out anything you might need that day.
