I am in the process of making a 408 block long by 56 block wide cruise ship, I am hoping to attempt to model it after the carnival project pinnacle but so far only have a 4 deck hull, i'm not sure how tall the superstructure will be but I so far have put a movie theater a mess hall with a stage the bathroom and stairs up to the next decks for that section and a place to look over that mess hall. Also a large artificial forest with a stone slab path through it and HUGE pool with that path making a bridge over it. I am then planning a large amount of rooms another bathroom and another stair case up to the next decks since all of the previously listed things are in a big 2 deck high area. The next 2 decks up will probably have more bathrooms some restaurants more rooms another big pool a shopping area and a sun room located so a direct sun beam can come from way up at the top down through the probably total of 16 decks. But the sun room will be on the 4th deck and the 16 decks doesnt include underwater "work" decks. This is a cruise ship that someday I would love to stay on. There will also be a "floating" path going over the artificial forest to help which will then open into a huge room over the giant pool with a glass wall all the way across looking at the forest. By the way the forest is 54 by 98 blocks and has a river with an island running through the middle lit by glowstone covering the entire river bed. The river runs into that pool and has dolphins swimming in it. The island has a tiny pond on its highest point which causes a 1 block tall waterfall into a cascading area into the pool. Which is I believe is 52 by 41 blocks. Both the forest and the pool have glowstone running up and down the walls and arching over them. The movie theater and mess hall and bathroom and hallway to all of them all have gild trimmed doorways. The staircase up to the floor looking over the mess hall, AKA deck 2, will then turn and continue up to deck 3, then turn and continue onto deck 4 where it will likely stop and a different staircase will continue up all the other floors, and same with the stair case in the back past the pool that will link most of the lower deck rooms and suites. Most of deck 3 will be rooms and most will be in the back. Only decks 3 and 4 will have any rooms in the front and they will consist of 4 master suites on each deck and 6 rooms. On deck 4 towards the center there will be 6 suites on each side with roofed balconies and all 1,2,3,&4 will have 10 small rooms on each side in the half, each one 10 blocks by 20 blocks. Then 1 master suite on each side closer to the pools each one 20 by 20 blocks. In the very back oddly curved area will be large baloconies with stairs behind them that lead between them and lead eventually up to the space between the two halves of the rear third of the super structure where it splits and is shadowed by the red and blue glass that was part of the carnival project pinnacle cruise. From the top there will be a mine cart track "slide" all the way down to the 5th deck, or alos known as the first deck aabove the hull, and the one with a very large shopping mall area in the middle of the two separate areas of boat in the back. There will be stairs between every balcony that will accompany every room on those rear half "spikes". And in front of the huge funnel with colored glass that will shade and protect the shopping mall, there will be a large gap dropping all the way down to that sun room on the 4th deck. Every deck it passes through will be able to look across up or down the huge tube, over fences.every floor will have a bathroom in the front and back, and decks 6 to 8 up front will have a humongous museum, and from decks 9 to 11 directly centered will be a zoo of equal size. Located right behind the museum and another one right between the tube to the sun room and shopping mall area will be stairs all the way up from deck 5 to deck however high it gets. Up top will cover above the split room so you can walk around the funnel and go inside to walk over the clear glass floor to bath in the middle, also it will cover the disc-ish shape around the hole to the sun room and all the way to a set of wide semi rectangular decks above the bridge, but in the middle from 3 decks below all the way up will be a hole to accommodate for the artificial mountain also shown on the pinnacle. Around it will be a "moat" fed by a stream leading directly to a interior food court pool. Small bridges will allow you to cross the moat and climb the mountain, on top of which you will be almost higher than the tip of the funnel. There will be 2 more smaller movie theaters, 1 more large mess hall, though not as large, and lots of rooms. 5 food courts and 3 restaurants, the mountain, the zoo, the museum, probably 4 or more pools, 3 waterparks, the 1-2 deck one, the mountain one, and one on deck 10 with a huge glass enclosed slide down to deck 5 where that mall is. 2 shopping centers, the mall one between the 2 halves, and one just behind the food court with the pool to the mountain, the restaurants will be on deck 5 in the front, on deck 6 behind the museum, and on deck 13, one below the mountain deck. Decks 12 and 13 will have mostly rooms but a pool in the middle of deck 12 with diving boards from deck 13, which will simply have a large hole in the middle. So this confirms that if there are 3 decks above where the mountain starts, and it starts 1 deck above deck 13, then the ship is 18 decks. 17 interior decks and then you can go on the roof deck, AKA the 18th deck. Please respond with your large ship builds and ideas! :)
