P&O Ferries, Dover to Calais

Not the fastest way to cross the English Channel, but can be fun. Check-in, passport control and security are faster than at Heathrow, but still take at least half an hour. On board the top deck, you are compensated on a sunny day with great views of the striking White Cliffs of Dover as you chug out of the harbour and miles of golden sand as you arrive in Calais. Below deck, you can jostle with backpackers, lorry drivers and families for something to eat or somewhere to sit. Alternatively, you can wind away the 90-minute crossing by browsing through the shop, watching cartoons in the kids' lounge or playing arcade games, but try to avoid using the sometimes filthy toilets. If you aren't in a hurry, good value at £100 return for a family and a car. 6/10
