They dive more for time. 50-60(ish) minute dives and everyone surfaced together. I'm sure the three of you could all be in the same group.Thank you. Do you know how they run the group? i.e lets say 8 people get into the water, if any member of the group is out of air before everybody else they the group all need to surface? We have a group of 3 members, not sure if we can dive together as a small group.
