Caravanning is like Marmite - you either love it or hate it. Being firmly entrenched in the latter category, I expected to be unimpressed by this play.

However, John Godber's reputation goes before him, and, as writer/director, he produces a comedy of some substance, delving in a deft and unstuffy way beneath the surface of his characters.

In this Hull Truck production, two couples - one middle-class teachers with an interest in Gilbert and Sullivan, the other with a cultural knowledge extended only to bashing out songs at karaoke - share a pitch on a caravan site.

What develops during the course of the play suggests that, despite their obvious outward differences, they are not so dissimilar after all.

Julie Higginson, James Hornsby, Kate Baines and Adrian Hood ably deliver defined, keenly observed portrayals in what amounts to an extremely pleasant, if not groundbreaking, evening.
