With children, the best holidays are not the fullest ones. They are the ones where you do not have to negotiate every journey.
Mornings belong to the beach
Go early, come back before noon: the sand is still cool, the beach quiet, and the house becomes an air-conditioned refuge once the sun bites.
Afternoons, the pool
A few steps away, no sand, no waves, and watchable from a sun lounger: the residence pool is the obvious answer to the hot hours.
In the evening you eat outside under the pergola. The outdoor kitchen keeps the house cool and stretches the evening out on its own.
