Old San Juan is the historic core of San Juan. Although this eight by ten block district is part of San Juan, it is quite geographically and culturally distinct from the rest of the city. It occupies the western half of the islet of San Juan, which it shares with Puerta de Tierra. As this is a tourist destination, English is relatively common, but not universally spoken.
Plaza Las Américas has more than 300 stores including the only Macy’s in the Caribbean, the largest JCPenney in the chain, a 327,000 square-foot Sears and Sears Brand Central and a 40,000 square-foot Forever 21, among other stores.
Las Croabas Lagoon in Fajardo has 500,000 to 700,000 of bioluminescent dinoflagellates ( a plankton) per gallon, so when you wave your hand through the water you trigger so many of them that your hand lights up with a thousand tiny stars. There are many companies that offer kayak trips into the bioluminescent lagoon from the small fishing village of Las Croabas. It may be worth the trip to Vieques Island to be able to swim in the bioluminescense!.
