We rented a scooter and drove around the island. It's beautiful and we found the Bahamian people extremely nice and helpful. We had a problem with our scooter and thought we might not make it to the ship, so we didn't see as much of it as we would have liked. ( No fault of Carnival).
The town of LaRomana is quite poverty stricken, sad, dirty and kind of depressing. We spent some time in town then went on the zip line excursion, which was fun. Most people went on tours or to the beach.
Curacao is a lovely island. We enjoyed sightseeing around, and went to the Hota Caves where interesting history took place, and saw some bats and indigenous cave carvings. The island is hilly and lush. Curacoans are friendly people. We enjoyed walking over the pontoon bridge later in the evening in Willemstad. We avoided shopping but if you're going to, this is the place. There are tons of shops in an indoor/outdoor mall & entertainment area.
We rented a car and went on our own. It's a short drive from Orenjestad and well worth it. It's a beautiful park with varied scenery: hills, desert, shrubbery, shoreline, dunes, rocky formations, and a cave with indigenous paintings.
Atlantis Submarine Rating:
I loved the Atlantis sub. From the ship you walk as a group a short distance to the dock where you go on a motorboat tot he submarine. You sit back to back at your porthole and see all kinds of interesting sea life and a couple of shipwrecks. The guide tells you what to look for and I was especially lucky to sit up front next to the assistant, Chris, who spotted many fish and pointed them out to me. It lasts about an hour underwater. On the way back they show you some sights of Aruba and see the beautiful shoreline.
