My parents own a couple timeshares down near San Diego, Ca. that I believe are also through RCI. They love to go down there and golf, and do whatever older :smile: people do. They use it about once a month for a few days at a time. They love it down there and I have been too, and it seems OK.
The only problem I see is when you want to go somewhere else (Europe for example) you need to have a place booked like a year and a half in advance, or longer. The good places book up early and are almost impossible to trade through the network with the one you own. I don't know about you, but I have no idea what I will be doing in 12 months from now, let alone trying to stay at a sub par "condo" on the wrong side of Hawaii. If you plan to use the "location" you buy at, then yea, go for it, but if you think you will just be trading points and going everywhere but the place you own, I would suggest against it.
My parents go once a month, and get their money's worth. If you can do that too, it could be good for you. Just don't let them "convince" you how easy it is to trade you property, or points for other more desirable locations. My parents have the blue (or maybe it's red), which is the best property all year round that RCI offers, and we were just barely able to get a reservation in Kauai 14 months in advance.
I would just save the money, put it in the bank and make a reservation at a nice condo at a place of your location, not some rundown place off the beaten path like RCI will put you in.
Just my opinion.
