Thanks for the responses everyone.

I will lose my Platinum Status here in the next month or so. I do have the CO Presidential Plus card if that helps at all with entering the Clubs.

Second, thanks for the advice on walking through the parking garage. I'm not sure what I will do as I have about a 4 hour layover, so time is not an issue. I'd like to go wherever I can go to a lounge with my PPlus Card.
