Grenada Honeymoon questions

Hi everyone! Originally my fiancé and I were leaning towards St. Lucia for our honeymoon in November but it seems like everything I am reading says Grenada is just as beautiful, with better food, easier transport options and without the crazy price tag!! Any advice from people who have traveled there? We're not really drinkers but are big foodies so that is most important – is it worth it to do an all inclusive? I found Laluna and it looks amazing but haven't seen many reviews on it in here! Any insight would be appreciated!
