Is this possible? Can i do it in Fajardo instead of Vieques as I dont have the option to stay overnight in Vieques. Also I just figured that i am there only on full moon nights. But i don't know if i will ever visit PR again. Do you recommend i should still do it in Fajardo? Are there options to come back from Vieques so that i can stay the night in San Juan.. Any tour companies in Fajardo that you can recommend? Should I book it n advance or can i get it once i reach there?
