Caribbean Honeymoon

Hi all! My fiancé and I are starting to plan our honeymoon. We’ve pretty much solidified that we want to do the Caribbean but now need to decide where exactly in the Caribbean. We’re thinking either St. Thomas/St. Johns(US Virgin Islands), St.Barts or St.Lucia. Has anyone honeymooned or vacationed at these locations? Where would you recommend for a honeymoon out of those options? Open to any and all advice or insight. Thanks so much!
