Please recommend a place to visit within 2 hours drive of Calais

Was due to drive to the South of France this summer via Eurotunnel, this holiday is now cancelled due to coronavirus , so I’m considering whether to cancel Eurotunnel booking or move it to bank holiday weekend in August.
Is there anywhere nice to go not too far from the Eurotunnel?
Would Le Touquet be an option?

this townhouse in Boulogne-Sur-Mer (25 mins ish drive from the Eurotunnel) might be an option?

you are near the marina, the town centre (with shops and restaurants), and a beach. You could order an online shop for once you arrive into the house (with breakfasts and snacks for taking to the beach etc), and then plan to walk to the restaurants for lunch and dinner.

Le Touquet, Saint Valery Sur Somme, Le Croty all easily within 2 hours and lovely beach towns. Le Croty and Saint Valery have a steam train that connects them and beautiful seaside walks.
