Are you wanting daycare during the day or overnight boarding facilities? Ft. Meade is a bit of a drive, but has an amazing and fairly new facility. I don't know if they do "daycare" but we have boarded there overnight before. Their rates are EXTREMELY reasonable compared to other local businesses.
White Plains is a ways south of Andrews on 301 (about 15 miles or 20 minute drive from Andrews FamCamp), but it also has a very nice daycare and boarding facility called The Playful Pup. I am currently using them for my boarding needs because they are closer to me than Ft. Meade.
