So I am going to try to buy peak weeks in ... Kahana ... for the RCI TPU's. My intention is to leverage the points or TPU's to get more places to stay for longer times in other spots. ... Looks like they are studios and studio lockouts
Kahana Falls has studios, 1 BRs and 2 BRs. Based on listings, I suspect that most are 1 BRs.
If you look at ebay completed (not necessarily sold) listings, you'll see that a number never even got a $1 bid. So, I'd suggest looking at your "exit strategy" whether 10, 20, 30, etc. years down the road.
Hawaii TS are known to be decent "traders" but expensive in terms of $ per TPU. I looked at four 1-BR listings on Redweek and each listed a different MF. I looked on eBay and their numbers didn't match either. So, I don't know what the MF cost is. Perhaps if you are still interested, ask on TUG or call the management company.
Kahana Falls was sold as deeded weeks and were affiliated with Interval (plus also RCI). About 10 years ago the mgmt co. started converting weeks to TPU's through RCI. The conversion cost was pretty high - - like several thousand dollars. It is my understanding that upon sale, that the TPU points conversion does not convey. So, you may end up buying for points and ending up with "weeks". Maybe I'm right or maybe I'm wrong. But if you are attempting to "leverage points or TPU's to get to more places", you need to be 100% certain of what you're getting.
