How would i label all the hardware in a hotel's network connection, Completed home drawing but, still curious

Every 15ft probably would be a bit overkill for network equipment. Modern access points can handle a lot of clients, and have a decent range before noticeable speed drops...For instance the access points we use have a range of 400 ft so even if you spaced them every 200 ft, you'd never be more than 100' from one, and that would be more than enough. My guess is it may have more to do with smoke detectors, carbon monoxide detector, etc - a safety and security type device where close proximity to each room would matter greatly. No on dies cause of slow wifi (but it sure feels like we might), but possibly because of carbon monoxide, yes.

Going back to your original question, how to label, well that's up to you. I personally, like to break down the network into smaller and smaller areas.

For instance, the front desk might be it's own area, a wall port might a number, and the number of ports on that wall plate might be a letter. So on your switch, you might have FD-1-A, FD-1-B, FD-1-C, FD-1-D, which would be a 4 port wall plate in the front desk. If you had a second wall plate, that one might be FD-2-A and FD-2-B. Your admin back office might be A-1-A, and so on. 1st floor might be 1F-1-A, 1F-1-B, 1F-2-A and so on, 2nd floor 2F-1-A and so on.

My knowing the code, you could look at a label on the switch and know the general area of the hotel, Front Desk, Admin, 1st Floor, 2nd Floor, the general area in the larger area that cable/equipment will be located (1, 2, 3, etc), and which port in that area its' actually connected to.

I just wired up a small office, and followed this. One office I labeled 1-A, 1-B, 1-C, 1-D, 1-E and the next was 2-A, 2-B, 2-C, 2-D, etc. I also labeled the faceplates where the termination happens so its very easy to know which cable, on which switch, runs to which port on the wall in the office.
