I think the solo cruisers have more to be concerned about than couples (even though we are paying for 2 people on most cruises). I checked my January cruise to S.A. and Antarctica and I picked a cabin that is a quad. I wanted the location. I would not want a forward cabin for this particular cruise since that is where you feel the most motion and we do the Drake Passage. I don't think there are any VA's there, at least not on deck 5. But I book far enough in advance that I can carefully pick the location I want. If they move me to a less desirable location (in my opinion) then I would want some compensation or be able to cancel without a penalty. Even "Cancel for Any Reason" insurance doesn't give a full refund. My next cruise I am in a cabin that is not a triple or quad so unless they start telling us solo's we can't book at all, I am safe. That will probably be my last cruise.
