Yes. I'm in charge of booking a ski trip for ~15 friends each year, and the amount of reading between the lines I have to do to make sure everyone has a comfortable place to sleep is crazy.
Tons of places count sofas/pullouts/day beds in the "Sleeps # of People", and they often count the temporary beds as space for 2. So you'll see places that say, Sleeps 16, but there are only 3 or 4 real beds.
Hotels have it right up front: 2 Queens. Period.
