re: Honeymoon - Bahamas or St Lucia

In St. Lucia I'd recommend Sugar Beach. Its in between the Pitons and on the beach. I'm not an all inclusive guy, but food options in St. Lucia are limited. If you want something different look up the mountain at Ladera. It only has three walls and has great views. I've heard good things about cap Maison but I haven't been there. If money isn't an option, check out jade mountain.
I haven't done the Bahamas, but may be going this fall.
