I'd go on another Quark cruise, but with significantly different expectations from a photography point of view.

Bob, could you elaborate on this point?
An ordinary ("normal") cruise isn't going to get on the public address system at 4:00 a.m. to wake everyone up to point out some wonderful dawn light on the mountain side. I doubt many cruise ship captains will sail through The Gullet (67° 6'38.60"S 67°32'29.40"W, where the channel is only half a mile, or .66 km, wide) to provide exceptional photo ops. These events happened because of the nature of Michael's charter, Michael's guiding hand, and the rather singular focus of the passengers, characteristics unlikely to be present on most cruises. And such events matched or exceeded my expectations.
Not that other Quark cruises aren't without merit, they're just different. I wouldn't expect the kind of photo opportunities this cruise offered. I would expect similar excellence from the expedition staff and ship's crew.
Now for a really, really stark contrast, compare a Royal Carribean cruise and this Luminous Landscape workshop and cruise!
