We have friends who own at a Hyatt resort in Puerto Rico. They'd like to purchase something else within II that would increase their number of points available for trade. I am not at all familiar with the Hyatt point system. I'm assuming that they might need to purchase another Hyatt property to stay within the points system. Are their other types of resorts (Starwood, etc) that they can also purchase to increase the number of points they can combine into their Hyatt II account? Any suggestions on resorts to research or where to find reasonable resales?
