Sri Lanka or South Africa? Galapagos and Botswana other contenders

Having a hard time picking! I've been to SA before but on a gals trip. When I visited i thought it would be ideal for a honeymoon – wine beaches mountains amazing food!!!

Alternatively Sri Lanka neither of us have been to and have heard great things!

We are also toying with Galapagos (again visited solo and loved it), and have been recommended Botswana by friends –

We are after lots of chill time, but some adventure, and some great meals and date nights. We have both traveled extensively so we want somewhere cultural and memorable !!
