I’m keen (amazingly) so is my son to have a weeks trip with me in late June post college end of term, he’s going away with friends to Spain in Aug so happy to head away with me before his trip. I need advice on destinations as I think he’ll get bored of a holiday in the sun with not much to see or do nearby. I don’t particularly want to hire a car so somewhere coastal but with things to see or do. Any recommendations for overseas please not the UK.
