Flood, my class was small, just me, my buddy and the instructor. We got off the platform for all 4 dives, something my instructor said doesn't always happen. It depends on how all of the students master the basic tasks. All told we were in the water for an average of 30 minutes for each dive, the first one a little shorter, the last one a little longer. I would highly suggest you get used to wearing gloves before you go out, if you can. It makes things a little more difficult. It really is up to your instructor and the students. Between dives, we filled out our log books, changed tanks, and discussed what we had just done and what we were doing next.
As far as a camera goes, I'm looking for a simple, PHD camera to start out with so I can take snap shots. I am going back to Dutch this sunday morning, I want to work on bouyancy control and other stuff. I am meeting a couple of folks from the board there, check under the Wreck Valley forum. I was heading over today, but we just got nailed with some severe thunderstorms and I decided to save the vacation time until one day next week.
