We went on the Epic and unlike most of the other smaller ships this ships layout was bad and no conducive to travel around the ship. The casino allowed smoking which could be smelled in a restaurant and venues. The shops were in the middle of the ship and when a lot of people were shopping it did not allow people to flow by to get from one end to the ship to the other. You had to go thru the shops.
On the pool deck when they were performing and people gathering to listen or dance again you could not get around all the people standing there. For a disabled person it was not very good getting around.
The staterooms layout was so bad it is hard to explain. The bathroom toilet was in one section and the shower was on the other side. A curtain was provided, and doors to close off. I could not go out in the balcony without waking up my wife. there was no curtain to segregate the room.
