I did it with my kids. They had a blast and I think I even had more fun!! We had a strict no elevators rule with the game.....so we got a LOT of exercise! Helped work off all the food! I think a group of ladies would really have fun with it...especially with bar stops in between! You can take as long as you want...even waiting a few days in between..it saves the game on your badge. If you were doing it no stop....depending on how fast you move through the ship...I would guess maybe 2 hours from start to finish. That is a best guess though. Depends on how many other people are playing at the time. You may have to wait for them to finish using the picture first. You may have to spend longer moving through the ship depending on the time of day.... Grab a badge, your "notepad" and follow your clues!! Have fun!! Great excercise, great fun and a great way to really learn the ship!
