My brother and his girlfriend took their first cruise on Epic last fall, and he had this to say:
"We went on the Epic. The ship itself was amazing! Blue man group show was free and awesome! The Circ dinner show was well worth the $20, the slide was fun, dueling piano bar was awesome. Over all the ship was very impressive!
The issues we had were with unfriendly service. Particularly in the free restaurants, and our room attendant.
Be prepared to spend some serious money on the ship! Alcohol is super expensive! $6-9 per drink! And you can spend some money at the pay restaurants as well, not that bad though, $20 is the most for a fine dining 5 course meal."
