All BH trips from Ambergris and Caulker will usually have a min dive number as it’s a full day trip 2-3 hrs there and back depending where you are leaving from and trips will be cancelled/pushed if there aren’t enough divers. It’s usually something like 16 but Belize pro are going with 11 today as they didn’t go last week. They need to make the trip worth it. People generally don’t realize that it isn’t a simple daily run out. Takes Lots of gas, 3/4 divemasters and a captain for the full day etc.if the weather is bad, the crossing can be very rough and you need a big boat to deal with the chop. I’m afraid that I don’t know too much about the ratios on caulker dive ops, but I wouldn’t dive with any shop on the cayes who had higher than 6 divers per DM absolute max, if I was at a diving resort with diving included as a package I would probably be annoyed if that ratio was any higher than 4 divers per DM. You can be disappointed if you come for a slow week and no shop has enough divers to justify the blue hole trip, so no one goes....it’s quite rare though, If that happens you can always do private or helicopter and dive package, but that is in the $1000’s+ Ops may be more regular from caulker though as it’s a ‘bit’ closer. Still a full day trip though. The blue hole is a ‘day trip’ as opposed to a ‘dive site’
