Honeymoon Ideas: Sandals Royal Barbados, Sandals Grenada or Sandals Grande Antigua

So my fiance and I are trying to get ideas as to where we'd like to go for our honeymoon. We're getting married on October 2nd, 2020 and are looking to leave that Monday after. Right now we're looking at Sandals Royal Barbados, Sandals Grenada, and Sandals Grande Antigua. I love the beach; crystal blue water, white sand, and a nice walking distance and my fiance likes the pool; so if we can find a nice balance with both that would be great. We really like rooms with a gorgeous view; also that have direct access to the pool such as a walk-out room or even a walk-out to the beach. We would like to do maybe snorkeling or scuba diving and really just be able to see the beauty the Southern Caribbean has to offer as we have never been to the Southern Caribbean before. We seem to like Grenada but would like to get opinions from others. Any input or advice anyone has would be greatly appreciated, especially if anyone has ever been to all 3. Thank you so much!
