Via Linda our on the ground wonderwoman:
So recap, the teams went up into the space needle – that order was the brothers, then, the father, son, then the beards
when they came down, they went around the corner to the Chihuly Garden. That order was father, son, brothers, who ended up going the wrong direction at first, and then several minutes later, the beards, who ended up going the wrong direction and went in from another gate.
When they left, they ran to their cars, got a map and then went by where the clue box was to look at the Maps. The departure order was father son immediately followed by the beards, then about five minutes later the brothers.
