Exciting things to do with 5 year old

[*summer*]

Can anybody recommend any children activities to do at any of these ports. We'd normally get off, have a look around and find a park but would rather do with a funfair, waterpark, amusement place, fun or interactive museums. Or if there are any beaches quite close that have sunbeds, toilets, kids stuff etc. The ports are Nice, Palma (overnight so plenty of time), Toulon, Cadiz, Malaga. We're really looking for fun and exciting stuff otherwise 5 year old son would rather stay on the ship [emoji85]!! Thanks in advance

A guidebook should point you in the right direction....I suggest a guidebook whenever you go somewhere you've never been! Libraries have guidebooks, and it won't cost a penny!
