If I am comprehending correctly, if you are a party of 4, it seems like the cost difference between car ride and bus is not so bad such that it might make sense to use a car in many cases. Do most car/taxi services handle a party of 4 in a single car easily? If we just walked to the taxi stand at LGW, would there be plenty of options to get a single car ride for 4?
