Extremely indecisive couple looking for warm weather and romance! Mallorca, Maldives, Greece, Italy, St. Lucia, or Bora Bora?

My Fiancè and I are looking to honeymoon August 28th-September 15th. As the title states, we are extremely indecisive and are looking for some help here! If you honeymooned at any of these places, what was your experience? Pros/Cons and the beautiful memory your honeymoon you will always look back to. Please share! Our budget is 15k and we don't mind a long flight. Hoping to get some good insight here and get some butterflies from some of the stories 🙂
