I need to find out what is the least hassle for a family (2 adults, 2 kids),traveling into London from Gatwick airport. Although I understand the Gatwick Express is the method of choice, I am concerned about hauling luggage, along with two tired kids, onto a train after an overnight flight. Any other suggestions? Are there shuttle buses that go to hotels in the city (as there are in the US?). Even paying a bit more will be preferable to hauling cranky, tired kids. Not the way I want to start our vacation!
