Hello fdsteixeira
I would think that kind of camp should count. The conditions are that it is valid for
Teilnehmer:innen von «Jugend + Sport»-Veranstaltungen, J+S-Lagern sowie von weiteren Lagern und Veranstaltungen mit offiziellem Charakter (Trainingslager, Musiklager usw.).
or translated to english
Participants of ‘Jugend + Sport’-Events [A Swiss initiative to promote youth activities], J+S-Camps as well as other camps and events with a official-like character (training camps, music camps etc).
I think your camp qualifies as a such. You can purchase it for mutliple days in a row, but you need to reserve spaces in any vehicle you intend to take and you need to stick to that schedule.
In long distance trains, there will be seats reserved for your group so that you can sit together. On local trains, there are not designated seats but you still have to reserve (The same goes for busses). It might not be possible for the bus companies or the train companies to provide big enough vehicles, in which case you will not be able to reserve seats and the ticket can not be used on that lines. In order to arrange all that, it is easiest to call the SBB contact center at +41 848 44 66 88 (0.08 CHF per minute).
