I have an expiring Gold Passport Platinum Extras Certificate (expires 3/31/13). I am not able to stay at a Hyatt by this expiration time and would rather someone from here enjoy it. It says not transferable, but I can't see it link to anything in my account. Private Message me an address for mailing and it's yours. First Message Gets it. Will send via snail mail ASAP. I won't go into the details of what this certification is; if you are here you should know. Have a great stay!
