Is deck 5 considered mid ship??
It is only if you are in the middle of the ship when "looking at it" from front to back.
The Magic and Wonder are big ships with many decks and the terminology can help you find your way around a little easier.
Terminolgy lesson
Forward is the front of the ship
Mid Ship is the middle of the ship
Aft is the back end of the ship
Starboard is the right hand side of the ship (when facing forward)
Port is the left hand side of the ship (when facing forward)
Deck 1 is the lowest passenger deck on the ship (decks A, B, C and D are below deck 1 and are crew only areas). Deck 1 is also where you will disembark the ship when in port (except at the terminal at port canaveral)
Deck 8 is the highest deck with staterooms
Deck 9 is the "fun in the sun" deck with the pools, ping pong, topsiders/BBB restaurant along with many other fast food and drink outlets.
Deck 10 is the swimming pool overlook deck along with the sports court.
Deck 11 is "The Stack" on the Magic (teen hang out) and on the Wonder its the ESPN Skybox
So when you see something in the navigator that you want to participate in, it will tell you the location name and you have to know where that location is.
If you want to go to Beat Street (Magic) / Route 66 (Wonder) its on deck 3 Forward. Going to Animators pallet, its deck 4 aft. Want to shoot some hoops, the sports court is deck 10 forward. The family club, Studio Sea is deck 4 mid ship. The Oceaneers Lab is deck 5 forward and the Oceaneers Club is deck 5 Mid ship. Etc, etc, etc.
There are lifts (elevators) and stairways forward, mid and aft. Stateroom numbers are 4 digits. First digit (1000's position) is the deck number. Second digit (100's position) is a 0 or 1 on the Port side and 5 or 6 on the Starboard side. The 10's and 1's positions is your room number. The numbers are ascending from forward to aft. So you know you are aft if the 100's position is a 1 or 6.
