We will be in WDW for 6 nights in August...(18-24)...the first 3 nights we will be staying at Poly GVC, so I am just going to pay for those nights...the last 3 nights (sun,mon,tues) we'll be at the BWV...we usually rent the 1 bedroom units there, but now I am starting to learn about the point rentals here...I do have a few questions though...First off, are there any other fees involved other than the point rental? (taxes etc)...secondly, how do I know if there are units available at the BWV for rental?...I don't want to but points and then find out there are no units available...last question (for now)...I see that the Grand Villa for those 3 nights would be 88 points a night...so 3 nights would be 264 points...I have seen up to 250 points for sale from any one seller...if I bought the 250 points, how would I get the reamining 24 points to cover it??...do I have to buy 24 points from another person??...Thanks for all info!!
