Disable Book now button until everything is filled

[Valentina R]

It would be great if the Book now button would be disabled by default until the day, slot and required addons are not selected.

I know it also depends on the theme, but if there was a class that users could apply to the button (if theme doesn't have it by default), that would help a lot.
