We walked to El Morro and explored the fort for about an hour. Definitely worth a visit. Afterward we rode the free trolley into the shopping area of Old San Juan and stopped in Starbucks for wifi and then CVS for a few items.
We went to Sapphire Bay this time. We walked over to the Havensight Mall, across from the pier, and caught a cab there rather than being herded onto the cabs right by the pier. From past experience, we knew we didn't want to sit and wait for them to fill up with 10-12 passengers and then stop at every beach along the way. We shared with 2 other couples all going to Sapphire. It was $10 pp each way and all of us met up with the driver for the return trip. She even took "the scenic route" for us to see Magens Bay on our return, stopping at an overlook for photos. Sapphire Bay is beautiful. Lounge chairs were $7 each and we didn't need an umbrella, as there were sea grape trees for shade. DH said the snorkeling was fantastic. We stayed about 4 hours.
We took a cab to Valley Church Beach, $8 pp each way. Lounge chairs were $5 each, and we didn't need umbrellas here either, as there was plenty of natural shade. The sand was not very smooth -- plenty of shells and prickly things from the trees. We ate lunch at The Nest, the beach restaurant/bar, which was not over-priced and offered wifi. Restrooms were decent, a short walk beyond the restaurant. In general I don't love Antigua. The cabbie and vendors are very aggressive.
I took the water taxi to the shopping area while DH took a cab to Orient Beach. After some shopping I had lunch (and free wifi) at one of the restaurants on the boardwalk.
We booked an independent excursion with Cosol's Tours, along with a number of people from our Roll Call. It was a full day -- almost 7 hours -- seeing the whole island including a volcano and mud baths, the twin pitons, Jalousie beach, and many wonderful photo opps, plus breakfast and lunch of local fare. Highly recommend it.
