I got stuck on the MMMBT when coming back from the airport once before. We were there for about two hours, until 1:00am. Luckly my mom seems to keep 3 day's worth of snacks in her purse.

If I got stuck there again in this kind of cold, I think that Heatsheets would come in handy. The driver is SOL, it's a one person size. ^_^
