I was looking at "no-where" cruises on Expedia, and there seems to be very few, most of them being 1 night. Definately not recommended - look at thsi itinerary, for example.
Day Ports of call Arrival time Departure time
01 New York, New York --- 5:00 PM
02 New York, New York 7:00 AM ---
Hehe
If you are spending a night in New York, and want a "unique" hotel experience, this might be an interesting idea
Inside Cabin $149pp
Oceanview $179pp
Balcony $189pp
Suite $229pp
