Yes, the door to the outside walking track is right next to the room. However, it is the single door with the port hole window not the automatic sliding door. The automatic sliding door is adjacent to the starboard elevators. (You can touch both your cabin door and the single door standing outside your cabin door). We enjoyed the location. Pop out that door, down the walking track to the aft of the ship, down one level on the stairs and you are at the Windjammer. Easy access to the Solarium also. Solarium closed at 8pm so noise was not an issue while sleeping. Room 1838 is close to the elevators to pop down to entertainment venues. Take the elevators to Deck 5 and cross the Promenade to Main Dining Rooms. Deck 4 is an outside route from the forward elevators to the Main Dining Rooms.
We did not feel the ocean, as far as swaying with the waves, any more than the lower levels. We could hear the ocean very well from the balcony.
