It's hassle free
Going abroad can be exciting, and it can also be a chore. That's particularly true if you have young children, as anyone who has ever tried to sneak a car seat onto the plane as hand luggage will know.
Stay in England, on the other hand, and you can shove it all on the car, and the only baggage limit on trains is how much you can squeeze into the overhead racks. Plus, there's no danger of your motor hitting turbulence!
