I have an RCI free membership with one of my vacation clubs and I do not think it is of any value. When the free membership expires, I will not renew. The getaways are not of high quality.Are you aware that with 112.00/ month for 3 years you could easily get 10 to 18 weeks of vacation time, with no further commitment if you do not want to?
Just buy a RCI timeshare on ebay with low maintenance fees, 300 or less per year, preferably in Vegas, since you seem to enjoy going there. That should cost you less $100.
Then join RCI, around $100 per year, and use their "last call" rental program for weekly timeshare rentals costing between $200 and 300.
If you rent at an average of $250 per week, you should be able to squeeze 16 weeks out of the $4000 you would pay, fewer weeks if you pay more, more weeks if you pay less.
So, my advice is: drop your vacation club, and do not consider Westgate. There are way cheaper alternatives out there that get you the same thing.
