I spoke with Mike and "Walkins" are welcome. I would recommend contacting the hotel however and making mention that you are with the 355th Fighter Group Reunion -- then check prices == the rate for the reunion is not necessarily lower than the rate you can get online so check before finalizing. I learned there is no free breakfast. Hot "To Go" breakfasts are available but there is a charge for that service. I found a McDonalds about two blocks from the hotel and there may be other breakfast spots.

Also I learned there are vendors along the Mall in DC that will store luggage if you need that service and I will on Sunday. Get the Luggage Hero app for you cell phone. More info on their website: luggagehero.com
