cmculp,
If you were Gold elite at the time, the upgrade should have been complimentary. I went through the hoops with the Wailea Renaissance about the same issue and elevated it to Mr. Marriott's office, but unfortunately nothing could be done since a couple weeks after my stay they were deflagged. I never received the upgrade nor my elite benefit guarantee even though I started the process while I was staying at the hotel as is required by the T&Cs.
