We really enjoy cruising and we have always, repeat, always enjoyed NCL cruises. But this was our first cruise on a mega ship, and you should know that I use both a wheelchair and a scooter. Whoever designed the Epic knew nothing about people with disabilities. This is definitely a "do not go near it" vessel.
I say this recognizing that our accessible cabin was quite large. But come on, in this day and age of CPAPs, electric scooters and other medical devices, one outlet in a room is ridiculous. My wife went to guest services and got an extension cord at no charge, but once she was back to the room it would not reach the CPAP. And when two cords were attached, the scooter plug would not fit into the remaining outlet on the cord. At least the steward was able to tape the cords to the floor so I would not trip on them.
Then there is getting to where you want to eat. We like the venues that are included in the price as our budget is very limited. We were toward the aft of the ship and were near the elevators. But we could not go down to the fifth deck without getting out at 6, going to the midship elevators, then down to five to go to the one non-dress up MDR. Or, to go up to the Garden Cafe, one had to maneuver a obstacle course and ask people to get up from their poolside lounge chairs so I could get by on the scooter. At least the Garden Cafe had two accessible seating areas. These were nice, but were always filled with people who did not need to sit there. And then, one had to wait and wait on tables to be cleared, and wait some more to get clean silverware. It was obvious that staff size has been reduced.
