Analogies should be handled with care. What is common in one country might be inappropriate or irrelevant in another. It is therefore important to use analogies that your target market is familiar with.
Walt Disney is an excellent example of how this can be done successfully. In the US, the Walt Disney World Resort is described as “half the size of Rhode Island”. But the analogy requires some knowledge of US geography.
So in Japan, the park is said to be “the size of the Tokyo subway system”, and in the UK, “the size of greater Manchester”. This makes the audience feel more included – and the copy more effective.
