Perhaps Pinel if you want to be in the water. A small boat ride of about 5 minutes to get there. Hikers can walk across the island and your husband would be just a few steps from the water in a shaded chair. They will bring you everything you need right to your chair. Did it yesterday. Had a decent pizza for lunch and just hung out. Was not overly crowded yesterday. Perhaps a bit more today with locals but there is plenty of room. Enjoy whatever you do.
