Thanks John for the input...
It's great to hear from someone that is crazy enough to do such coral runs. I can live with 75%, but I am shooting for 90%. I wonder how they do the shipment from Bali to the LFS. Some suggested shipping coral using wet newspaper

Anyway, I was thinking about changing 25% of the water half way through my trip

. In the mean time, I will shop for heat packs and clean out my styrofoam box...
