Has anyone had any experience with one day cruises? Seems like some sort of repositioning sailing. I have seem some rather compelling rates departing out of Seattle into Vancouver BC, of course with port taxes exceeding the room charge ($29 + $30.95 tax), up to $79 for a high end room.

Seems to be cheaper than dinner, movie, hotel, etc.

I was curious if they scrimp heavily on these cruises, what the occupancy rates were like, if they had full food service, and if it was an entertaining method of getting to canada for the weekend.
