I am thinking of booking haven, devon cliffs for the school summer holidays. I will not have a car and was wondering what the public transport is like for getting around? I have 3 children, who will be 10,8 &4, they are keen to go to diggerland, the model railway place, crealy themepark and dartmouth castle. will this be practical, Ie will they have to sit on a bus for 2hrs each way and is it expensive? All advice on public transport will be greatly appreciated, thanks.
