What does "all the way" mean here? What is Max trying to say by that?

Here, "all the way" means completely or as much as possible. He's saying that he'd only choose to go to the beach - "surf and sand" - all the time or as much as possible. Ex: If I had to choose between chocolate and vanilla ice cream, I'd choose chocolate ice cream, all the way! Ex: The party is going to be Harry Potter themed, all the way.
