I haven’t done it, I woke up today and my girlfriend was insisting for Grenada 😀
So we couldn’t decide for sure. Your suggestion helps me a lot.
From those I heard/read Grenada is the most beautiful of them and probably I will go only once to Caribbean, so I think this is the right one.
Also if i get bored on Grenada I can go a day trip to some small islands there with ferry. Am I missing anything?
