We once went with 13 people and nothing was said. Some of the 13 were small children. I still have a Powerpoint diagram of where everyone was to sleep enroute and at the Fort. At the Fort we had a side room with high-rise mattresses, which made it bearable. A wonderful time was had by all. We kept several different schedules, so we weren't always together, which helped. All that said, NEVER AGAIN!!!
