It's been about 10 years since we used the pack and play at a cabin, but at that time, we set it up in the bedroom at the end of the bunks. If the pack and plays are stil the same size as back then, it will fit in the bedroom.
We put our pack and play at the end of the full size bed in the bedroom. The only thing was you couldn't go out the back door which we didn't care about.
We used the front door in the kitchen.
You could put the crib in the living area if you don't use the murphy bed. We used the Murphy bed so we put the pack in play in between the bed and the bunk beds in the bedroom.
