They all sound lovely - I've been to the lakes most recently, but all of the places at some point in my life - my family holidays as a child were this sort of thing but hubby and I went to the lakes last year.
Only thing these days if you're taking the dog is whether you'll be allowed on the beach with him(?) - a lot of places don't let you in summer anymore. Might be worth checking before you go cos, if your dog is anything like my childhood one, it will hate being near the beach and not being able to run around on it.
Hope you enjoy x
