We recently returned from our stay at Club Intrawest Blackcomb. When we booked, I asked Member Services about the nightly option instead of the whole week through II. As I recall, the nightly points were quite high, and given the new set point schedule, it would have been more points to do something like 5 nights as opposed to the whole week through II. If you call Member Services, they will walk you through it.
