I emailed conceirge to get some clarification on what Marriott benefits are even still honored. Unfortunately the upgrade from sedan to limo has been discontinued. I stated that I am Gold Elite at Marriott and she indicated that I may use the marriott checkin to the left of the front desk area. Is this the same as Identity Platinum check in? I'm Identity Gold and last time i stayed at Cosmo was over a year ago on marriott points. I asked these questions in an email reply, still awaiting a response.
