Later this month we'll have about 3 hours to kill at DCA, after a 6 day D.C. visit, and was wondering what lounge you'd recommend? We each have a Priority Club membership (thanks to Platinum Amex card), which allows up to 3 free lounge visits per year. We can access US, NW, CO, DL & UA lounges, I believe. Free booze is a plus so I guess that rules out UA & US. Add free wi-fi & that would "seal the deal". :) We'll be flying DL with no checked luggage (I hope). Looks like CO & DL are in the same terminal so one of those might be the easiest.
