Has anyone dealt with National Timeshare Help Center (NTHC) before? They're at www.timesharehelp.net. They responded to a post I had (I wanted to rent a 2dr at Embassy Kaanapali in Sept) and had a good rental rate, so I agreed. I sent them a cashier's check and am now having trouble getting confirmation from Embassy that the reservation is actually under my name. Every time I call NTHC I get excuses which are not checked out when I call Embassy to verify.
