Wife and I are late 30's. Did our first SXM trip 4 years ago with an equally aggressive schedule and did everything on our list except dinner in Grand Case, but that was only because we found other places that were more convenient to Terres Basses (Dreams, le Sand, Mario Bistro, Tropicana, Le Cigale, Sol E Luna, Ma Ti Beah, Layla's).

Don't miss Happy Bay. The hike from Friar's is less than 10 minutes for the young and fit (even carrying a cooler and umbrella in flip flops). Also highly recommend Cupecoy at sunset with a bottle of wine and some hors d'oeuvre. A truly memorable experience.

Have a great time!
