I finally booked a combo snorkel/dive trip. I founf this guys from trip advisor. Seems to be a pretty good deal. It is from 9am-noon. the divers cost $95 for 2 dive and all their equipment. And $25 to snorkel. Includes water, juice, soda, fruits, chips and sweets. For an extra $30 we are having beer and mixed drinks. He has a website at Caboticket.com - That's the ticket! his name is Traun.
If anyone needs any other info let me know.
