I think it's Best Western offering the "3 stays and get 1 free night or 2 stays and get 1 free night if you pay with Mastercard".
We've come across some very nice Best Westerns thru-out the country...it seems they often have more local flavor (sometimes that's good, sometimes not!) than the other chains. Usually the rates are very good and include some sort of breakfast. We've found the AAA tour book descriptions to be pretty fair.
We haven't seen much in the way of benefits with the Gold Crown Club...my favorite was a parking place right next to the front door at the BW in Redondo Beach along with a free bike rental!
