I have one certificate good for a one day adult ticket to either Universal park. I got the certificate as a park of a hotel rewards program and intended to use it last week when we went to Disney. But, it never happened and I can't use it by the time it expires on December 31st. The certificate is addressed to me but it does not state anywhere on it that an id is required or that it is nontransferable. There's no guarantee that it will work but if you're interested in giving it a try leave a message here with your email address and I'll get back to you.
