We just realized that our flight into London will be into Gatwick not Heathrow. We had assumed Heathrow. Our B&B offers a taxi subsidy from either airports but I'm wondering if it will be just as fast (and less expensive) to take the Gatwick Express to Victoria Station than take the tube to our B&B in Harrow? From the looks of things Gatwick is farther away than Heathrow - therefore it would cost more to take a taxi? Any information you would have would be greatly appreciated!
