I'm sorry your friend was not comfortable in the Kids Zone with some noises. Those noises usually come from the auto humidifier, because it's very dry up there. Also the hot-water heater was just serviced, so shouldn't be a problem anymore. Unfortunately Big Bear has hard water issues & needs to be serviced more frequently. As far as the sleeping arrangements, we've never had a problem sleeping 16 guests. There are 5 bedrooms: Pine Room with a King & Futon, Bear Room with a Queen, Lake Room with a Queen, Cliffs Edge with 2 twins (put together to make a King), Kids Zone with a Queen, Full, Twin & sofa sleeper & Game Room has a sofa sleeper. I'm so glad you enjoyed the daytime of the Cabin, we love it as well. The great location & the game room is wonderful entertainment!
