We dove this site in 2002 with 12 divers and two guides. It was crowed and my wife who had less than 10 dives and no night dives, freaked out. I had 30 dives of experience and 3 previous night dives and at the time I wasn't experienced enough to know that some people don't adapt as easily to night dives. I found the diving incredible, but I would not recommend this site for your first night dive. It was a little too claustrophobic since the pier supports aren't evenly spaced and it's a popular dive. If you've done a night dive before, definitely do this, it was terrific!
