In the South, a sleeping porch was often for the summer only. It had lots of windows or was just a big porch with screens, and was usually on a second floor. Our sorority house had its sleeping porch on the third floor. I thought it was wierd at first, but grew quickly to LOVE it. Nobody lived on third - just the chapter room and closets up there - so it was quiet and you could sleep any time, day or night. Alarm clocks were necessary, but you were expected to turn them off quickly. The windows stayed open year-round - and it DOES get cold in Tuscaloosa, Alabama - but you just cuddled up in your electric blanket. Daughter's sorority house at UA (DZ, not DG) has sleeping porches, but there are 2 on each floor along with rooms, so they get a good bit of noise. She hated them. But she's spoiled and pampered!
