What is the split of the other divers? Are the six of them together? Three couples who don't know each other? They may not want to split up either.
Take ALL of the divers, "us" & "them", and divide us up between three boats - regardless of two or three tank and we all have more room on all dives and nobody changes boats, just gets roomier - the resort just has to run three boats all day instead of just the morning....
Let me clarify again....
The boat will run 3 boats in the am. They will run 2 boats in the afternoon.
The only decision is whether we put all the 2 tank divers on one boat and split the 3 tank divers between the other two boats
or
We put half of our divers on one boat
The other half our divers on a 2nd boat
and all NON-SD divers on the 3rd boat
There will be 3 boats no matter what....the only decision now is if we have SDer's on 2 boats or 3.
