IMHO St. Barths is over rated. I used to vacation there back in the day. It's just another island. There are certainly more beautiful islands. It's dry, desert.
I like the idea of Mombasa with a safari. I've tried to get to Mombasa a couple of times, but never made it. I was planning to get there in Jan of this year.
Male and the Seychelles have always attracted me. (I don't think you can get to Male on Skyteam though).
