For the last several years I have done nothing through RCI except get EVs and LCs for other people. Two of the couples have the 5-Year Guest Pass now. One even got multiple units for his high school group.
This is the best use we have ever made of RCI, with the lowest 1-bedroom rental rates now at $239. Thousands of units available where you would expect them to be and nothing affordable where you would expect that to be.
Lots of skepticism the first time for each of those I help, but lots of satisfaction when they find out it's for real.
I have not been keeping track, but I just looked at our RCI history; the last 22 I've done have been for other people. The most expensive, tax and Guest Certificate included, was $355. Actually, that only goes back to 2015, and I started doing them for one of my "cousins" in 2013.
Our last deposit was a 2014 week.
