We are considering purchasing a resale annual Ko Olina timeshare, but are becoming more confused about the point system/week system, the more we read. We love Ko Olina, but would also love to trade out weeks for other destinations on occasion. How difficult is this going to be in the future? I had another owner tell me she purchased a Branson timeshare years ago from Marriott because it was the least expensive one, but has never vacationed there because she has always traded destinations. Would we be better off doing likewise.....purchasing a less expensive one and trying to get a week in Ko Olina? Thank you!
