I was there about 30 years ago (twice) and loved it!! Spend some time on the beach, they are great! pink sand. You can rent mopeds and see the whole island at your own pace. Driving on the other side of the road takes some getting used to, though, when I came to a traffic circle I had to stop and think about it for a few minutes.
Not sure if they still have the perfume factory, that was neat. The whole island is just beautiful and historic, I would go back again in a heartbeat. Have fun!!
