You cant bank your borrowed points but can you bank points from your current use year. Example ) let say we have 140 points and we need 252 to do a week 1bdrm BCV. So we borrow 112 points but then decide were are gonna do a 2 bedroom Sun-Thurs so we only need 170 so we only would have needed to borrow 30 points. Can we then bank 110 points back to the following use year saying we are not giving them back just banking from what we have this year ?
