My family will be passing through the U.K. in May and will be staying for about a week with some friends in the Coventry area of England. What is worth seeing while we are in this part of the world? I've seen that the coronation of Prince Charles is happening around that same time, so that might play a role in our plans if the normal sightseeing places get extra busy or crowded. We are not confined to England and are willing to travel around some if not too difficult. Any advice is most welcomed. Thanks
