I just purchased an encore package at Surf Watch to return next January or February. The package was $999 and I was able to enroll my Harbour Point and Sunset Pointe weeks into the points program. My Harbour Point week was bought from Marriott and my Sunset Pointe week was bought externally. I figure the winter week is worth $200 (xyz or AC price) and they are also giving me $200 in Marriott reward $. So basically I am paying $600 to enroll my weeks in the program. I will never deposit my weeks for points..... I simply joined for the exchange fee benefits. Worth it or not? Also do you have to pay for xyz weeks since they are considered an exchange?
