Seems like I get "conditional" status right away. Is not getting the card right away a big deal? If I give number when I check-in, or when I make the reservation, wouldn't they see on their screen what my status is?

"On behalf of Marriott Rewards Guest Services, please allow me to extend an offer to you to conditionally upgrade your status to the Gold Elite level. This new status would be valid through October 31, 2011; however, an updated membership card would not be processed until the following terms have been met.

In order to maintain this status, you must stay 12 paid nights beginning with the date the upgrade is processed, through October 31, 2011. This is a one-time offer, and would be effective within 24 to 48 hours of your acceptance of this upgrade offer."
