The minimum point add-on is 25 if you're paying cash, 50 if you're financing. However, that does not entitle you to the 11 month booking window for ALL your points. You get the 11 month window for the points at that resort only. For instance, you have 150 points at OKW and 100 points at VB. You want to book a stay requiring 200 points at VB. You could book as many nights as 100 points would get you at 11 months out. You could use banking/borrowing with your VB points to book the entire stay; you could book the remaining nights at OKW and attempt to switch them at 7 months out, or you could take your chances and wait for the 7 month window to book the rest of your stay with the OKW points. Make sense?
