This summer I will be going to a wedding in Paris at the beginning of July. Our plan was to just do Paris originally, but we are now considering adding London at the beginning or the French riviera for some beach time before or after. For London, it seems relatively straightforward to do that first and take the Eurostar train to Paris. However, I am not sure how it would work to get to some nice Mediterranean beach town for a few days. Also, is it going to be too overpriced and overpacked in the beginning of August to even consider adding the beach component?
Would consider some smaller town with character and some sights rather than a more popular destination for the Riviera. Is this doable by train and without a car? Also, does it make sense to fly out of a southern airport (star and end is NYC, prefer EWR).
What towns should I consider for beach and possibly other site seeing?
