I want help with this too please help us because im getting annoyed now because this has
troubled me

Passports are in the scenery.

scenery - Path extras - other

they're in scenry in the path extras and other simplez *meerkat thing*

Does anyone know what they do? I have a few around the park, like in the space area for
0.60 and 2 tokens they can get the alien bobble hat but i was wondering where they can get
more tokens/stamps?

In a pdf i found on the internet it says:

"passport stations

Listed among the path extras is an element called passport stations. Peeps are given a
passport booklet as they enter the park. If peeps have their passport booklet stamped by
the required number of stations, they win a prize! You can specify how many stations are
required by using the passport station control panel. The ideal strategy for using
passport stations is to place them far apart at the far reaches of your park, giving peeps
a reason to visit all areas of your amusement park. "
