Do bear in mind that SouthCentral trains also run a service from London
Victoria to and from Gatwick Airport, which is cheaper than the Gatwick
Express, but almost as frequent.

This is true, but for the tourist, an extra couple of dollars for the
branded and easy-to-find service is probably well worth it. Even more so
in the evening rush hour.
