I stayed at AKV-Kidani in a studio last Aug. We had 3, plus a "baby" in a pack and play. You are allowed 4 plus the "under3," but I will warn you that it's a tight fit to pull out the sleeper and set up the PNP. We had to rearrange and squish chairs in corners to make it all fit. And before we could even consider breakfast, we had to have everything cleaned up and put away in the morning.
