I was on this itinerary in May. If you do not have mobility issues then these are to good excursions. In Puerto Plata, which ended up being Amber Cove for us but basically the same port, we did the Damajagua Waterfalls. This is were you slide down waterfalls. This was one our of favorite excursion ever. It is quite a hike to get to the falls but they stop you every 5 minutes to give you a rest. In Tortola we did the Virgin Gorda and Baths. This is basically a beach day but you get to walk and climb through really cool rock formations on your way to the beach. On GSC we rented a Silver Cove Ocean Cabana. It was nice and private. For most of the day it was only me and my daughter in the water in our area, which had waves (the Lagoon did not have any waves). I always like Cabanas since they give you a place to drop your stuff and guaranteed shade. I know there are other Cabanas not in Silver Cove that are cheaper or if you do not want to be away from the action. Silver Cove is a private area for only Silver Cove guests and they cart you to the area since it is on one end of the island.
