The offer is valid for all vehicle types, "dutchflyer" (rail and sail) and foot passenger bookings, as well as all elements of booking from cabins to pre-booked meals and Stena Plus lounge access.
The 15% discount on travel to Holland offer means a family of four (two adults, two children aged four to 15) can save £24.90 on the lead-in price for a return crossing to Holland with their car and includes unlimited luggage allowance.
The same family would save £35.10 for a return to take Stena Line's "dutchflyer" (rail and sail) option, which includes rail travel from any National Express East Anglia station to any NS rail station within the Netherlands.
The offer includes travel on the two largest Superferries in the world, the Stena Hollandica and Stena Britannica, which launched in May and October respectively last year. Departing twice daily, crossings with Stena Line from Harwich to the Hook of Holland take approximately 6.5 hours with a choice of day or night sailings in each direction.
National Ferry Fortnight has been arranged by the Passenger Shipping Association to help consumers learn about the investments that ferry companies make in order to improve the travelling services for passengers. It also celebrates the benefits of traveling by ferry, highlighting the unlimited luggage allowance, onboard space and facilities and absence of surcharges, lengthy pre-departure check-in times, taxes and queues. The fortnight runs from 14th May till the 28th of May 2011.
