This has always been a sticking point for us. Beside my wife and I, I have two young girls and we like to have their grand mothers come with us when they're able. We also wanted private space so we're not all on top of each other.
After two travel trailers we ended up a fifth wheel with a front living area. We can sleep 6 on beds comfortably and throw a queen air mattress on the floor and put up a curtain if needed.
But I absolutely agree. Our first bunk house stated it could sleep 10. In reality it was two kids and maybe three adults.
