I was wondering if there is any way to sync my wife and my Marriott Credit cards so that at renewal the Cat5 certificates will expire at the same time. This would give us the flexibility of doing a free mini getaway at a nice hotel.

My renewal date is April, hers will arrive shortly in the mail so it's going to be sometime in December. I could wait with the activation, but I am unsure if this even has any affect as far as the anniversary is concerned.

Alternatively is Marriott open to extend the expiration date on these certificates?
