Italy, Greece, Bora Bora, Mallorca? Looking for amazing scenery, great food, and romance.

My fiancé and I are planning a honeymoon between 8/27-9/15. Our budget is 15k max. The places we’ve considered are in the title but we are so indecisive. Who’s went on a honeymoon in these places and what was your experience? Pro’s, con’s, and whatever summary that is forever burned into your memory about your honeymoon. Hoping to get some amazing stories/recommendations here!
