A year ago, some folks learned the hard way that you need to click on the offer link and open a new account - then, after you have your new card, close the old account (consolidate the credit lines if you like).

Calling to "upgrade" didn't net all of the sign-up bennies.

I don't know if this has changed or not. In either case, you should get the recurring Free Night certs and the 15 nights' credit every time you pay the $65.
