We travelled on the Epic in February, 2011. Twenty-something travelers without children. This is our second cruise and first with Norwegian. We made all our reservations for entertainment and specialty dining prior to boarding. Ship was sailing at full capacity.
Overall, the experience was better than expected. Many of the complaints you hear about in these reviews are true, but the ship does redeem itself in several ways. Except the flaws, enjoy the cruise and just complain about improvements.
Embarkation was straight forward and efficient boarding the ship in under twenty minutes.
