Mostly because faster and cheaper building. They order glass, install it between floor and ceiling and can use bathroom immediately. With other types of walls you usually have to build frame, install insulation when you want also sound proofing, then put drywall, plaster it, paint it, install trim boards. Doing real wall is too much work so hotels can save money but same time ask more from customers for premium look as glass is shiny.
I don't know anything about construction, but is the difference that large? It seems like some of the tasks you added to the wall side would also apply to the glass side—you still gotta install it, if sound insulation matters to you then you wouldn't use glass either, and you still need the edging of the frame for glass which is the biggest part of the wall framing. All the drywall stuff, plaster, and painting is indeed more work. But I also think having large panes of glass is in general a more difficult, more expensive, and less versatile thing to purchase and keep around than the plaster and drywall you can get anywhere.
Anyways, not saying this isn't it, but it feels like the differences might be smaller.
I agree with you, I doubt it's about saving costs. When designing the hotel room and the hallways leading to the hotel rooms they are already doing framing, drywalling, plastering, painting, etc. All the materials, tools, skilled labour are already on the job site. The materials are cheap (the labour might not be). What's 1-2 more walls?
