This promo may be over already, but it's worth a shot. Text "HAMPTON" to 40491, you will receive a reply giving you a phone number to call to redeem for 10K HHonors points. The mailbox is full. Apparently you can e-mail firstname.lastname@example.org and supply your HHonors number to get the credits as well. This is not confirmed yet, but for 10K points for 30 seconds of effort, it's worth a try. Hat tip to the Travel Hacking Cartel by Chris Guillebau (I butchered his last name).
