I can't say for sure, but it seemed like they controlled which group went to which car pretty tightly. They definitely emphasized that you were not supposed to walk between cars during the ride. I don't know if they have a max group size, since we were only 3, but I can say for sure that only the people that were on our ride up were in our train car down. Definitely recommend them!Does this private company have a max number of people they will allow in one group? Are the people in your group the only ones allowed in your train car?
I'm trying to determine how to have the same experience of a less crowded train car. TIA
