i believe for the nite snorkel, it was $25 per person, but, being that i was solo, to go out, i had to pay $50 .definitely worth it, in my opinion...i did the day snorkel with geraldo and fido badillo on the catamaran...i believe their pier is 2 north of amigos del mar, across from lily's hotel...the owners of lily's can get in contact with them for you...they came and picked me up at the pier in front of my hotel, and dropped me off there too....this was an all day trip, with 2 snorkel stops....hol chan marine reserve and shark ray alley.....in between we stopped for lunch on caye caulker...rum punch is included on board...lunch isn't...$50 for the day
