Why Is There a Window here?

Question

i went to the beach and in the room when you go into the bathroom you look to your right and it was a window and if the curtain wasn't there everybody in the room could see you

Answer 1

Was there an exhaust fan in the bathroom?  I have been to a lot of warm weather beach motels and many of them depend on the window for fresh air instead installing exhaust fans.  You are already in a humid area, so opening the window isn't going to add a lot of that to your room, but it will be an inexpensive alternative to an entire building with exhausting ducts and fans.  

As far as everyone else in the room seeing you if there wasn't a curtain, that means the window is installed into an interior wall.  That to me means a remodel somewhere in the past.  Why would it bother anyone, other than natural curiosity?

Answer 2

I'm thinking they didn't want to get lonely while taking care of business.

Answer 3

possibly this bathroom was added on to the original house.
