Hello! I am going to Isla with my boyfriend Jan 4-9. I have a dilemma though, he is an avid and passionate diver and I am not certified. Does anyone know if the dive shops would do a deal where he dives and I snorkel? What dive sites are the best/ with the most marine life? Which dive shop would you recommend? I'm trying to get this set up for an X-mas present for him. I'll feel terrible if we go to Mexico and he can't dive because I'm not a diver. We aren't comfortable with me spending a day alone. Also, Delfin Dives looks like it has good prices but I can't find an e-mail to ask about the joint snorkel/dive deal. Does anybody have one for them? THank you!
