That would be my recommendation. You can do the 26 Glacier Cruise, which is a high-speed catamaran that hops from glacier to glacier to glacier, or Major Marine Tours, which uses a slower boat and enjoys a slower pace around fewer glaciers. I've only done the 26 Glacier Cruise; it was nice, and I'd have no issues recommending it. I've also heard good things about Major Marine. (There might be a third company, but if so, I forget its name.)
