We dove with Sea Saba in January. I didn't feel like it was a cattle call even a little bit. We had one day that the boat felt crowded topside because there were some non-divers who came out with us, but underwater I had plenty of room to go at my own pace, which is slow because my face is in the reef looking for my little macro buddies to take pictures of. I dove my air - we weren't limited to any certain amount of bottom time except on the night dives. I think I had 2-3 dives with 75-ish minutes when we were at shallower sites. If you don't want to stay "with" the group underwater, they didn't seem to care as long as you had a buddy and let them know you were going to go off a bit. None of the dive sites are so huge that you get too far away from the boat, anyway. I thought that dive staff on the boats for Sea Saba were some of the best I've had. Very friendly, very engaging, very accommodating. If you don't like how they're running the dives, ask for something different. We didn't want incredibly deep dives for the sake of going deep while some people in another group did and the next day we went out on separate boats so we could all do the diving we wanted to do.
