The Hyatt Points program (HPP) is a trust like Marriott Abound, with limited inventory so far and generally higher MFs per point (see below).
The original deeded HRC weeks (Hyatt Residence Club) are also a points system (unlike Marriott) - you can use your week (specific unit also) or use the points. You can purchase a deeded week resale and save a lot of cash, and resale still has all rights to use the points system. I use my points for a combination of shorter stays and Interval exchanges.
HPP owners have first access to their inventory, and HRC owners have first access to their inventory - then a six months out the other system has access. I have met HPP owners at resorts who are frustrated with lack of inventory and did not realize they will see a lot more at 6 months out because it is HRC inventory.
If you go on ebay you will find HPP resales are generally worthless because of restrictions they place on resales. In my opinion, HPP is an very bad deal and many other HRC owners on this board have voiced a similiar opinion over the years.
HRC weeks have the same MF no matter what the season - so a 2br 1300 point bronze week has the same MF at a resort as a 2200 point diamond week. You can often get a low season week for free and have more points than your 38K 1100 point deal - but the MFs are by points in HPP so the MF would likely be lower per point with their offer - but that is not saying much.
If you are interested in Hyatt timeshare points, i would consider a gold 1880, platinum 2000, or diamond 2200 point 2br deeded HRC week purchased resale. Aside from Maui, most of them will be well under 10k and likely under 5k to purchase with a better MF ratio on points. The lower the season, the less the cost to get in, but the MF cost per point rises with lower seasons. The MFs vary by resort, so some are better than others for MF cost per point.
