I've been reading through all these forums to determine whether to buy Wyndham or Worldmark and how much to buy. I'm inclined toward Worldmark because I live in S. CA and Worldmark has more on the Westcoast and would like to avoid exchanging through RCI as much as possible, but I know there are times I'll need to go through RCI and was wondering how many points are needed to get a prime (July/August), 2 bedroom week on the S. CA coast. The people who have posted exchanges seem to pay different amounts. Is this how it works? Does the amount you need to deposit change with every deposit, and you only exchange the number of points necessary to get the unit you want? Also, I was wondering if it exchanges better by depositing the points, or could it be a better exchange by actually booking a particular unit, that is highly desirable, and depositing that? I really want to know how many points I need to purchase to get 1 high demand 2-3 bedroom unit every 2-3 years.
