All ages are welcome at the Inn on Carleton. Please keep in mind the rooms have a max occupancy of two persons and the Inn is not designed for young children.
Sorry, but I don't know. We have been there about 6 times and never saw any children though.
Although the website may not state “no children”, the rooms are really only for two, plus your child would need to have a refined palette for the exquisite breakfast at tables that are set up specifically for up to two guests per room.
Contact the innkeepers, they are wonderful and will either answer your question and even suggest an alternative place to stay.
