I plan on making my first reservation using points at BCVs for travel next fall. I plan to stay in a 1BR for 20 nights. I am aware of the 11 month window for home resort members, but what I'm unsure about is the earliest day that I'll be permitted to make the reservation. Is there a calculator on the internet that can assist in calculating the exact date(ala the dining PS calculator)? Also, is the 11 month window based on check-in or check-out date? Does the 11 month window force me to make weekly reservations at a time or will they allow em to book all three weeks at once(even though the 2nd and 3rd weeks will be outside the 11 month window when I make the first). My dates are fixed so I really do not want to miss out on the opportuntiy. I just want to mark it in the calendar and not think about it until the earliest possible date allowed. What would be the best way to approach this? Should I book it a week at a time if it's based on the check-out date?
