I really appreciated hearing about this offer! Just placed two orders, back to back, on my husband's amex #, then my own amex #. Amex notification of $30 rebate came immediately in my our email account for both purchases! Yea!
My husband's ticket purchase confirmation email from undercovertourist came shortly after, but my email required me to call undercovertourist to verify the purchase and my identity. The woman I spoke with was very nice and said my purchase with them was probably flagged because I made two separate purchases in two different names from the same computer, same email, etc. No problem, though, as she approved my purchase and I soon received my purchase confirmation email. I've ordered my tix from undercovertourist for years and have been very pleased with the service! Using the Amex offer on their site has yielded us 5-day park tickets for the price of 3-day tickets!
