I am a single mum to a 3 year old with very fair skin, and neither of us are very good with heat. I am a teacher and can only go on my summer holiday in late July or August - would love to go abroad but don't want to go anywhere too hot, so Spain, Italy, Greece etc all out. I was thinking France but I only really know Normandy/Brittany (which might well be disappointing, weather-wise) and the south of France, which will be too hot. Does anyone have any ideas or recommendations please?
