Apologies for the delay in posting an update on this. I posted a week ago about how to get a free year of hotel discounts.
At the time, a number of folks who had already signed up asked me how to extend their membership another year. I got an answer back from Club 1. If you send an e-mail to firstname.lastname@example.org letting them know you signed up for the free offer through my blog, they can extend your membership another year from now.
