Ok, I have been diving for a little while now, and convinced a few of my friends to get certified this spring (as soon as the ice is off the lakes). I lured them witht he promise of tropical weather, clear water, with coral and fish in colors Crayola never thought of. So where should we dive this summer for their first ocean dives? Local shops have group trips to Bonaire, Cozumel, Cayman, etc., and we certainly could book our own vacation just about anywhere. Given the fact that they are new to diving, and money IS a factor, where can I take them to really "set the hook" and keep them diving?
