Direct Ferries does not operate any ferry or train
services as such services are provided by the ferry and train
operators. When you make a booking for a ferry or train, we act
as an agent for the Operators in making that booking with you.
This means that you have entered into a contract with the
relevant ferry or train Operator, which will be the party
responsible for providing the ferry or train service to you.
