My teen daughter and I had a great week on the Norwegian Epic the week of August 21st.
We had a basic balcony cabin, which may have been too cramped for three, if my husband would have joined us, but for the two of us it was fine. We had an angled/forward-facing balcony, which was great, and a bit larger than a regular balcony.
Service across the board was excellent. I felt the staff was trying to be pleasing everywhere on the ship.
Cabin 11172 - small balcony cabin with a big angled balcony facing forward - I would suggest this for two people only!
