The Bioluminescent Bay is on the other side of Puerto Rico from where the ships dock. While I did this excursion on my own from the island of Vieques (an out island off
PR), you will be obviously going to the nature reserve's lagoon in El Faro (it is one of the 3 bioluminescent bays in
PR). Having named this one of the most memorable excursions of my travels - it is WELL worth the $79 cost and the time required to get there. By all means, "GO for it"!
