Was the first time we cruised with Norwegian and very likely the last.
The cruise line policy includes many extra charges that make the value for the money poor. It starts with drinking water (!), the cruise offers for sale packages of NCL branded drinking water. If you want any other brand, you need to buy it from the bar where the price (including automatically 20% service) comes to over $6. 20% service is for handing you the bottle.
Specialty restaurants are extra. Best choices for shore tours are sold at a price too high for the level of this cruise. The activities may become overcrowded in particular in shore tours.
