Mother and Daughter Looking Forward to the Sun

Hello, we are looking forward to summer and want to go to the coast in France or Germany. Other suggestions are also welcome. A nudist holiday is being considered, where sightseeing should not be neglected, as well as playing tennis or volleyball. A resort with leisure activities such as courses and creative workshops is also conceivable. Usually, we cook ourselves and rarely go to restaurants. We are 18 and 42. And who are you? Maybe the Netherlands or Denmark would also be an option. If you have ideas, let us know. Families or a couple are also welcome, though as mentioned, non-smokers are important. We are primarily vegetarian, but not every day.
