Bora bora or Safari

Hi, my fiance and I are trying to decide a destination for our September 2027 honeymoon. Our options are doing French Polynesian Moorea and Bora Bora or doing African safari paired with Mauritius. Our budget is around 20k. We have gone back and forth and right now landing that we might get a higher quality honeymoon doing bora bora due to how expensive even doing 3 nights safari is. Please let me know if you have any input!
