Congratulations in advance! What a great choice for a location, a wedding in paradise.
The laid back atmosphere ought to de-stress the entire wedding party. Then, since you don't have to travel for your honeymoon, you can just relax and enjoy right away.
I guess I'll have to ask all the honeymooning couples I meet "Are you BennyBoy and his bride?" That will either get me some strange looks, or start interesting conversations!
