I am running an eberron campaign, and the next major portion of it (hopefully levels 7-11 or so) will heavily feature a giant, cruise ship style airship. I now realize that there are very few readily available existing cruise ship shaped maps. Does anyone have advice about how I should put this thing together? I'm trying make it an immersive enough space that my players will want to spend a significant amount of time there.

Thanks in advance

Have you considered looking at the early 20th century Zeppelins? They were, after all, early 20th century German aerial luxury cruise ships.

I'd have a look at Airships.net, which gives all sorts of details about the design and layouts of the Hindenburg, the Graf Zeppelin, and others.

I don't think these are likely to fit exactly into a D&D setting - but it gives you a starting point, and a lot of inspiration to inform your design.

Sounds cool! :)

Also, if you want some techno-fantasy airship designs that could work, I'd suggest looking into Final Fantasy airship designs. Especially sine at least a few of them were used in-game as luxury travel options.

We are running the campaign in Eberron, so the techno-fantasy is exactly what is needed. That being said, I think there is some real cool potential with the Zeppelins and the encounters they allow. These are both great resources. Thank you!

I issue is that basic airships construction takes a long time (months) because of the resources needed to make one.
Soarwood, a limited annual supply.
Dragonshards (Khyber and Sibery), without the steady supply of both , constructing grinds to a halt.

It would take a lest a decade at a minimum, with no complications, to make a cruise sized airship.

 If you're just basing it on a cruise ship, there's a site called CruiseMapper with deck-by-deck maps for literally dozens of cruise ships.

I am not bashing it, the idea of it just made me think the logistics of making one.

Thanks for the help. The Cruisemapper was very helpful, and I did include a long backstory for the ship to account for the difficulty in building. THanks again

Check out Cze and Piku's post of a casino ship. I think you could adapt it as an airship easily enough.
