There were three of us on the cruise; myself, wife and 4 year old daughter. We boarded at Marseilles and there were very few people getting on. Check in was quick and easy (only 20-30 people getting on when we were there). Likewise, disembarking was easy due to limited number of people leaving.
We had a mini suite on deck 8 and it was nice. This was our first time on Norwegian and thus our first time on the Epic. Storage!!! Cupboard/shelves everywhere! The bathroom was kind of weird. As you walk in, the toilet was on the left, the shower on the right, and the enclosure was a translucent white. The balcony was very nice. deeper than we have experienced before though not as wide. I think I preferred this one since it was easier to arrange when two people were on the balcony.
We used many of the specialty restaurants which were nice but there are upcharges for everything. $20 per person just to go into the Ice Bar (even for my 4 year old daughter) which sucked. Rude service in the Moderno (sp?). Great service in the sushi restaurant (they made whatever my daughter wanted; very kid friendly and great attitude)
