Also Chuckles you can grab the gondola to the top of Paradise Point (close to the piers) and enjoy the beautiful views of the island surroundings and enjoy a drink while relaxing at the outdoor bar. We took a cab ride round trip to Magen's bay and enjoyed the beach which is protected from the usual waves. The snorkeling isn't great but the ride there gives you some great views as you wind around the hills. This is also nice as you can take the time you want. There is a fee to enter the area and there are restaurants and bars available.
Enjoy your anniversary !
