I read going early in the morning to Blue Grotto would be better but anyone ever gone late in the afternoon. Would it also be less busy? I have been to the Blue Grotto myself but this time I wanted my 2 teenage sons to experience
I know you don't spend much time in the Grotto but the thrill of getting there into the small boats then into the cave is neat. Any advice on things to do besides the Blue Grotto?
