I'm going to visit Lego House in Billund, though my hotel is in Kolding since it is cheaper. I plan to take the bus 166.
A one-way ticket seems to cost 72 dkk though it seems that there is also currently this ticket called "Trekantfest M" available at 75 dkk for a local art festival. Unfortunately the description is in Danish, so I'm not sure if this will indeed allow me to take bus 166 twice in the same day, i.e. whether the "lokal/regionalbusser" includes the bus 166.
The following is the description:
Should I buy this ticket? Is there any other day ticket that might be the most economic for me?
