The payment in each tour is it individual to a certain amount of people
Is your question related to http://triplelights.com/ ?
Almost all of the tours in TripleLights are charged by GROUP, not by person. So you will be paying a one-time fee that is good for the entire group. You can find this information in the tour page. Below the pric,e it indicates if it is per person or per group, and how many people can join.
I'd recommend sending TripleLights tours a message in this page: https://triplelights.com/contact
I hope this helps!
