This was our 9th cruise on NCL.
Embarkation once inside the building was swift but the taxis with 4,000 people clog the street and you stand in a long, cold line to get inside. Easy walk-off was swift but the line for taxis for 4,000 people stretched a NYC block. We took a black market cab.
Once aboard, the crowd was surprisingly disbursed. but now that NCL has gone public, they seem to nickel and dime you to death. You pay for many more entertainments and restaurants, the so-called lectures are diguised snake oil vendors. Stateroom movies are $7.99 or $14.99 for porno.The theater is disappointing, persons in front of you block the view. It is much too small and no overhead facilities to allow for acrobatics which are now performed in the 'tent'.(We did not go, $$$.) The Manhatten dining room dance floor is a waste of space whereas the well attended atrium is much too small.
The inside corridors are like the narrow Scottish roads, the person closest to a pull-off waits there while the other party passes.
The ship is slow, 22 knots which caused us to have only one hour of daylight after arriving in San Juan. Late arrival was blamed on the current and a speed limit in the 'right whale' zone. Don't waste your money on a ship's tour in San Juan unless you want to see it by night. (The Queen Mary I sailed on in 1951 cruised at 27 knts.)
The water park with many slides is nice.
You need your cabin key card to turn on the lights, a 'green' technique used in European hotels but we wondered why the steward always turned on the balcony light at night, not so 'green'.
