Working out a proper Cambridge-to-Kent weekend with three under-tens and no car took us about three tries. The first attempt lost a Saturday morning to a missed connection at St Pancras. The second was derailed by a flat iPad outside Faversham. The third went well enough that it is now the family default for a long weekend when no one fancies the M25.
Below is the version that worked. Train times we actually catch, snacks that survive the journey, and the one bit of kit nobody warns you about: how the data signal in your pocket goes from city-fast in London to genuinely patchy by the time you are pulling into Margate.
