I want to take the children away for a while in the summer. Ages 7 and 13. DP can't come as work for him looks super busy this summer. I want to go somewhere that's got a nice beach, opportunities for lovely walks , maybe some historical interest, somewhere i might be able to get a b&b or cheapish hotel (ideally I'd like a cottage but not sure budget will stretch at that time of year). Where ever it is needs to be accessible by train. Once I'm there, I dont really want to have to leave until we are going back if that makes sense.
If anyone can suggest somewhere please do.
