I currently have an offer for the Ko'Olina property in my inbox (1199 for 5 nights + 10k points) - I'm ASSUMING that if I I were interested in booking a second room, Marriott would be interested enough to send a second invite at the same rate my way? Or someone from FT would be, for another family member to book a second room?

I'm assuming the program covers all the Vacation club properties?
