On December 7-14, I cruised on the NCL Norwegian Pearl. I thought it was good cruise, but not a very good or great cruise, IMHO (In My Humble Opinion).
I have cruised on Royal Caribbean once, and on Carnival three times. I enjoyed my cruises those two previous cruiselines better than this NCL Pearl cruise.
My two biggest dissapointments, on this cruise, were the size of the stateroom (especially the bathroom) and the expenses onboard. IMHO, I did have a good cruise (as I said), but next time I would rather take a cruise on another cruiseline.
