We have 2 rooms that have couches.
1 is a small suite with a couch and King bed
The other suite has a couch and chair as well as the king bed and has 2 TVs that are separated by an armoire.
This is the largest room in the hotel.
We just stayed there with a 30 lb dog, and there was no problem leaving the dog. Does your dog stay in a crate? If your dog stays in a crate, you should not be a problem. If your dog has a problem being left alone, and barks, that will be a problem.
This hotel is definitely pet friendly, but I as a pet owner, your responsibilities, are to ensure the hotel is not damaged while you are gone.
Our dog does not bark when alone, and she stays in a crate, so we know she will be no problem when left in the room alone.
