We visit Margate, a traditional holiday resort on the Kent coast. In its heyday, it drew huge crowds of Londoners on vacation. Now, it thrives on the nostalgia. Dreamland is the country's oldest amusement park, with some of the rides dating back to just after World War One. And on the outskirts of Margate, we visit Hornby, a factory which makes train and aeroplane models that many of us had in our bedrooms.
