We recommend asking the passengers to pay for their own ferry fare at the ferry booth.
For ferries that require payment for both the passenger and the vehicle, we recommend asking passengers to pay for the full passenger fee, and a pro-rated portion of the vehicle fee.
Make sure to mention what the ferry cost will be in your trip description, and to be transparent with passengers that there will be an additional cost to be paid upon arrival at the ferry terminal.
For tolls, you can include the price in your trip by setting a price per seat at the higher margin. Make sure to mention in the trip description the toll fee is included when posting your trip.
