Hotel is where all the rooms are inside (one huge building), motel is where the entrances to the rooms are outside, and an inn is usually like a smaller hotel. They will usually have a restaurant on the ground floor and I think would be most commonly owned by a family

A hotel is a large house which has rooms that you can stay in, usually you have meals in the hotel as well as other facilities. A motel is more basic and may have separate buildings, service is minimal and food is not included. An inn is a pub which has rooms available to rent, similar to a hotel but the main business is selling drink and food. Hope this helps Bob
