Deciding between Jamaica, Grenada, and Cancun

Hi! We’re newly married and planning our honeymoon for May/June. We’ve narrowed to these three resorts: Excellence Oyster Bay, Le Blanc Cancun, and Sandals Grenada.

This is our first time doing all inclusive. Our priorities are a nice beach, good food, and nice room. We’re not super interested in activities and excursions, just want to relax and eat and drink in the sun.

Has anyone been? Or heard good or bad about any of the resorts? Any info is helpful!
