Looking for anyone that has used "Worldwide Travel Center" vacation certificate.?

I recently received a certificate for a "free" 2 night hotel stay from Worldwide Travel Center. This came after I made a charitable donation. Just from reading the certificate it seems like a scam but a Yahoo search of the company doesn't provide much information good or bad. I see that other people have asked the same question but I don't see any responses from someone that actually used the certificate or even tried to use it. I'd like to know if I should even waster my time with this certificate.
