Looking for a week in June, family of 4 including 2 teens after exams have finished. Just want to relax in the sun whilst they relax hiring stand up Paddle boards, boats or kayaks. Somewhere pretty not brash and a short flight from Manchester or close by? Everywhere seems so built up. I’m picturing a tranquil holiday to ease post exam stress. I don’t particularly want to hire a car as I’d rather just walk or use public transport. Any suggestions (I’ve searched for hours but not found anything that fits the bill) I’d rather self cater or small campsite lodge etc
