Full House

Full House is the sixth Bus Simulator 18 mission from the Official Map Extension, and 18th mission overall. This is the first mission to feature Sonnstein.

While Michael Bach remains the sole presenter, he makes a mention to Peter Baumann during the conversation.

Dialog
Michael Bach:
 * Hello, I've got good news. We've got access to Sonnstein stops.  It's a really lovely town and a popular tourist destination.  Peter Baumann has requested that we connect it to the airport and the business park.  He hopes that this will increase off-season bookings in Sonnstein.


 * We need to keep pollution at a minimum, so please only use CNG buses. Oh, and a heads-up:  Sonnstein's serpentine roads are quite narrow.  So please drive carefully.

Description
''Tim Wachowski bought a hotel in Sonnstein. Connect it and Sonnstein to Kerststadt, the business park and the airport.''

Objectives

 * Have a route that connects the following stops:
 * Airport
 * Sonnstein Main Square
 * Sonnstein (minimum 4 stops)
 * Business Park (minimum 4 stops)
 * Kerststadt (minimum 4 stops)
 * Drive the route with a CNG bus
 * Level up all Sonnstein stops to Level 7

Rewards
"Clean Air" Ad

Analysis

 * If the player has the Kerststadt to Business Park route (created in Student Exchange) around, or even better, has extended it to the Airport in the previous mission, then the best way to complete this mission is to reroute it and then drive it with a CNG bus.
 * It is not necessary to actually assign CNG buses to the route.
 * The annoying part of this mission would be having all Sonnstein stops connected to a single route in order to have the mission completed in one go. Alternatively, the player may choose to keep the main route stopping the minimum required number of Sonnstein stops, and divert one of the (less profitable) airport route to serve the remaining Sonnstein stops.
