We have just returned from a 7 day cruise on Norwegian Epic. There are so many things about the Epic that need attention I couldn't cover them all here.
First of all, I will say that the food was very good so no complaints there.
Entertainment: Some good, some ok. The Legends in Concert was VERY entertaining. Blue Man Group was ok but too slow paced and became boring. Dueling Pianos was fun.
mini suite is too small, poorly designed. Not enough drawer space.
Bathroom design missed the mark. A separation of commode and shower was ok but lavatory should have been placed in commode area, not in middle of the cabin.
