Don't feel like the "Lone Ranger"; you're not alone. I notice that you think that if you're upgraded you may get better service and opportunities to use your timeshare. Wrong! We purchased 156 points and we're having the same issues. We also had a similar issue with the timeshare usage we supposedly won. The timeshare that we were able to go to in Palm Springs was a "dump". That was the beginning of our realization that we were scammed into a bad situation that was very costly.
I would not be as disgusted if it were not for the fact that non-members can go to any particular timeshare website, make a reservation and get any date that they ask for. I've tried it. Their explanation is that all timeshares have a specified block of accommodations for members and a specified block of accommodations for non-members. It just so happens that non-member usage is lower than members. Yea, right!
I don't encourage anyone to purchase a timeshare. Save your money and go online, make a reservation to the timeshare you want to go to and be frustration free. I wish that enough of us could get together and file a class action law suit against these timeshare rip offs.
