As for how points "work" each night at each resort is given a point value. What that point value is depends on the day of the week (weekends are higher than weekdays), what season you are in (spring break higher than January), what size room you want (studio up ot 3 bedroom grand villa) and what type of view (standard, pool view, savana, etc.). Then you add up the points for all the nights you want to stay, and that's the total. As for renting, the owner will calculate that for you when you tell them the timeframe, size, etc. and then tell you what the cost is.
