Always a tough question. No grandkids yet but our 19 yo still camps with us half the time. We went with the bunkhouse room mostly because I wanted the full outside kitchen and we wanted our son to feel welcome to camp with us. My wife ha always had a rule of have enough beds available to sleep everyone without using the table and couch. Having the room has saved my oldest son and his wife once or twice when we camped in heavy rain and their tent got wet. They were able to easily move in for the night. When it is just the wife and I it makes a great changing room for us after showering or getting ready for the pool etc.
