The Dover to Calais service is P&O Ferries shortest route, with a crossing time of just 90 minutes. Five ships operate sailings throughout the day and one of P&O's key features is that it is very rare not to always find a ship in port loading for the next sailing. The ships can and do get very busy at peak periods so it is always advisable not only for the best prices but also to ensure you travel on the crossing you want. Do not worry if you arrive early, because if there is room on the next available sailing P&O will transfer your booking for you. Be aware that there is sometimes a charge for this if the sailing is in a different price band.

P&O Ferries operate a service called "Lite Nights", this is where on quieter crossings throughout the night not all facilities will be open. For example the Brassierie Restaurant and the Club Lounge are closed throughout the night.* During the day when the crossing is quieter some of the duplicated outlets, for example the Coffee Shops and Bars may be closed but there will always be one available. This is usually the outlets at the front of the ship which have the best sea views.

Despite the shortness of the crossing, P&O Ferries operate two minicruises on the route:

• The Car Park Shopper allows you to take your car onboard for the round trip to Calais allowing you to stock up on drink and gifts. These should be purchased on the outward crossing as they will be taken to the car whilst in Calais. On the "Spirit of Britain" and "Spirit of France" there are dedicated spaces on the car deck meaning that you do not have to move your car whilst in Calais. The other ships you may be required to move your car.
• Cruise a'la Carte allows you to enjoy the comforts and treats of the Club Lounge throughout the round trip and during the return crossing from Calais you will be able to enjoy a three course meal in the Brasserie Restaurant.

Alternatively you can just book a foot passenger return as a "non-lander", i.e. you remain onboard in Calais and travel back. These can be great value when combined with the savings on offer in the shops compared to in the United Kingdom.

* The Club Lounge is self-service on the "Spirit of Britain" and "Spirit of France" throughout the night so you can still enjoy the comforts of the Club Lounge. However the menu of food options are not available.
