Yes, crusise lines are shopped, seacaptain..LOL.. But, be careful what you wish for. I've heard they are VERY intense and not a relaxing vacation. I haven't completed a cruise for one company that I know offers them, but I did a restaurant and it took me hours just to do that report, so I'm figuring I'd run out of hours in the day to report a cruise trip.
BTW, I usually do between 5-8 shops per day, so 1,2 or 3 a day would be a light day for me. The number of shops you can get seems to be related to experience and location. I'm definitely doing way more shops now days than when I started almost ten years ago. The more companies you're signed up with, the larger the variety and more choices you'll have.
