Nobody in Hagerstown suspects the tourists taking selfies. That is exactly what HQ is counting on. In plain terms: your team explores on foot and takes on spy missions together. No guide means no one to impress and no one to blame. Just your crew and 2.5 hours of increasingly bold decisions. You do not need to be good at puzzles; you need people willing to have opinions, loudly, on a street corner. There may or may not be a double agent on your team. About 2.5 hours, 4 stops and roughly 2 km on foot. There is no guide, so nobody will make you stand still and listen. Somewhere, HQ is filing your mission report under 'surprisingly competent'. You take home the photos to prove it. Who it's for: friends, couples and families with teens; and private groups, from bachelor and hen nights to work teams and active over-55s. Book a private game for 1 to 8 players on a date you choose; a team of one works too. Bigger groups play as several private teams.
