We have 4 adults travel from Dover to Calais without a car on Aug 2.
I used http://www.poferries.com to check for fare.
The website shows GBP118 for four (or GBP29.5 each) for foot passenger without a car. There is only one quote listed.
However, for 4 adults with a car, to total is only GBP100, and there are choices for fixed or flexible fares.
I don't understand. Why 4 adults with a car is cheaper? Why isn't there any flexibility option for foot passengers?
