Taking your home on wheels across the water is wonderfully convenient. Just don't book it as though it's an ordinary car.
The tape measure comes first
Measure the motorhome including equipment that affects length and height. Use the correct vehicle category when comparing sailings, rather than selecting a standard car fare.
Think about your first campsite
A conveniently placed arrival port and a sensible sailing time can be more valuable than a small ticket saving. No one wants a punishing drive after a night at sea.
Don't expect access to the van at sea
Take documents, medication and overnight essentials with you. If you need accommodation onboard, check the actual ship's options and restrictions.
Routes to compare
A few things you might be wondering
Declare a bike rack?
Declare dimensions accurately and follow the booking flow.
Sleep in the motorhome?
Do not assume it is permitted; follow the operator's accommodation and vehicle-deck rules.
