I don't know about Hintermann, but on our trip, we had some dives which were very current-intensive and many which were not. If you want the hammerheads, apparently you have to go to where there is current, so we tried. I did use my reef stick to help myself on one of the dives. I don't like strong currents and I am NOT a real strong swimmer on scuba, so I figure unless you don't like moving water at all, any trip where I felt comfortable most of the time would suit almost anybody.
