All the people come along ARE divers. They’re just being picky of want to go to nice restaurant, and do something else at night.
We had a trip together to Key Largo two years ago, basically we finished our dive trip about 4-5 pm every day. By the time we woke up from our rest/nap, it was like 7 pm and there isn’t much to do in Key Largo, it was a bit of long drive to Miami from Key Largo. Back then we went to a couple restaurants at night, and that’s it. I don’t care much for the night activity as I would prefer to do night dive if possible. I wish I have some divers friends who’re not that picky in term of dive trip.
So, I think I should narrow it down to Key West?
Speaking of night dive, is it legal (for the boat) to let divers to dive at night without advance PADI? One of my friends did a night dive last year (I forgot where, but it’s in the US), and I told him he should get AOW since we want to do night dive, and he insist we don’t need to as long as there is a dive master. When I was in Malaysia, as soon as the divemaster found out I didn’t have AOW, he wouldn’t let me go below 18m during the day, and absolutely no night dive at all.
