Hey guys,
This rate is freely available to everyone, generally 15-20% off. It's through "Allied Business Network" which is free to join, so no question about eligibility. I use it all the time.

Either click through the link or use the numbers at the end of the link as a discount code on the Wyndham, etc., website. It may be better than AAA or AARP rates, not sure.
Safe Travels,
Doc
