I need a place to stay for a few nights en route to Lyn peninsular in Wales from London. It must be somewhere not too busy with holiday makers as I have a son with autism and a 20 month old abs we need an escape from crowds and not too much of a diversion. A beautiful spot with safe spaces to run wild would be great. I need to divide up the journey. I’m panicking about the trip so any suggestions would be hugely appreciated!
