David, I am in a similar situation at The Towers. We own 3 weeks. Only one of which is in the RCI pool. Thankfully I had already deposited that week.
However next month we were booked for the other two weeks. Maintenance fees paid and all. Not sure what will happen. And it's time for 2018 bills to be coming out. We will certainly not be happy to have lost this years usage, and have to pay for an uncertain next year. We are already discussing cutting our losses and walking away. :(
