OKay...heres my experience there:
I was doing my first dives in about year, which was also my first dives after OW class. They couldnt get my weight right, and I had trouble staying on bottom for the first dive. Second dive, I fought with all my strength to stay down, and was up to 41 pounds in my BC. I was wearing a farmer john suit which made me super bouyant anyway, but they still couldnt get me to be able to stay down. Next thing I know, I was at the surface, and didnt see any of the safety kayakers anywhere around, so I just started to a surface swim to what I believed to be back towards the dock. As I went around a corner, I saw I the dock, and about that time, the trailing saftey diver finally surfaced to see what was wrong. I had been gone from the group for about 10 minutes at this point. I thought that to be pretty long to be away from a group and nobody noticed. Anyway, I got back to the dock, and the guy working the dock asked me for my weight belt. Having a weight intergrated BC, I didnt have a weight belt. After I told him that, he told me "Well then, you are on your own" and he refused to help me out of the water and onto the dock. There are no stairs. I took off my BC, climbed up on the dock, and then fought to bring my BC on the dock as well, while this guy just watched. After a few minutes of struggeling with it, he finally came over to help. Just when we got it on the dock, the guys glasses fell off his face and went straight down about 150 foot. I was thinking in the back of my mind, "serves you right." At this point, I was so pissed, I didnt even do the third dive.
I spoke to one of the people topside, and they said that after the instructor died on the rebreather, they dont allow them anymore.
I can understand the lights, like someone mentioned earlier, thats how they communicate. There is plenty of lighting so lights really arent needed. You are also not allowed to have a dive knife, you can not bring your own tanks(and after walking that trail, you wouldnt want to) and they do not have Nitrox. You can upgrade from an AL80 to a ST95 I think is what they had.
As far as watching the video, I am learning that is pretty standard. I had to watch a video when I dove the springs down in Florida too.
