We took a trip on the Norwegian Epic ship, and booked the Haven suite for our honeymoon. It definitely was not worth the extra money. Below are pros and cons to the entire trip:
Pros
-The Haven bar areas and top decks were the redeeming quality of purchasing the suite. The bartenders were extremely nice, attentive, super friendly, and would wait on you hand and foot. The lady in the Haven bar was spectacular. Even when busy, she made sure everyone was taken care of, and made fantastic beverages.
Aboard our first cruise with Norwegian (on the Sky), we had an aft-facing suite with large balcony. It was fantastic! On the Norwegian Epic though, the suite left much to be desired (see above). We tried to purchase the same type of suite, and assumed the Haven suite we purchased would be very similar. Couldn't have been more incorrect. I would much prefer the Sky suite, which is also cheaper.
