That sucks, and is a BIG down side for the larger varied groups encountered on the LD boats. We had the same situation at Molokai on the 2nd dive but we'd already seen the hammerheads and were just floating in the blue after that. I would NOT have wanted to do that crossing in a zodiac or small boat however.
I will mention that on the back wall as well as at Molokai, the dives are live boat drift dives and with all those bodies in the water, I imagine it would be hard to let people surface where and when they want. I can see the scene with several groups of divers popping up at various places on the back wall in current with nothing but open ocean around should they be swept away from the island. Not so bad when there's 8 divers in the water, but juggling 24 - a boat captain's nightmare for sure!
We've had good luck with LD in general, and on moored sites we've been allowed to dive our tank but I would ALWAYS choose a small op if all things were equal especially for 'advanced' diving.
All that being said, if Tim guaranteed you could dive your tank, you should get a refund - that's a LOT of coin for a 30 minute dive!
