We are currently onboard the epic towards the end of our holiday. Let me first start by saying this cruise was suppose to be a competition prize, however I can honestly say if we won this experince again I wouldn't even bother taking the time off work for it.
Embarkation in Barcelona took 3 hours in the cruise terminal, diabolical organisation to say the least. Not a good start to a holiday...
To sum it up, the massive ship is like a zoo. There seems to be too many passengers than the capacity of the ship can handle. Often it is a struggle to find a seat or area that isn't crowded at any time. The whole organisation of the ship is poor, there is no order so it's like a free for all in the bars and restaurants. We have given up going to the buffet as people are pushing and shoving from all directions. God knows why the food is worse than what is served in hospitals.
Nice size balcony, however cabin is very narrow. The layout is very strange, as you can see the silhoutte of a person in the toliet or shower. Also the sink is very tiny and in the room which we didn't like.
