An owner of a timeshare week can rent out their week. Resorts that have excess inventory might rent out their extra weeks. Timeshares make great rentals, sometimes cheaper than a hotel. See http://www.myresortnetwork.com/search-vacation-rentals/index.asp
Items that are rented for a party, that are not supplied by the caterer itself or the client. Almost everything needed for an event, including china, stemware, utensils, cooking equipment, staff uniforms, furniture, etc can be rented.
