We are attending an event in Manchester this summer and want to make a road trip of it, with approx 3 days either side to explore the UK at a leisurely pace by car between London and Manchester. Kids aged 7+9. Looking for ideas of attractions and locations to stop. So far Stratford upon Avon, black country living museum, waterpark in stoke. Any other ideas please? Anywhere vaguely en route between London and Manchester.
