What do you mean by "Travel Companies"?

Travel companies on Zicasso (known as Zicasso Select Travel Companies) are tour operators and travel agents.

Tour operators: Companies which put together tour packages (i.e. organize a package which includes lodging and one or more other travel components such as air, car rental, tour guides, etc.) and operate the tours locally, including hiring local staff such as tour leaders, tour guides, and drivers. A tour package can be a customized private tour or an escorted tour with a group of other travelers on a structured itinerary (see “What are the types of travel arrangements available to me?”) Because they operate tours locally, they have deep local knowledge of a destination and often have access to volume discounts. Tour operators typically sell their tours directly to the public and/or through travel agents. Note that in some countries, particularly developing countries, tour operators also act as travel agencies, helping travelers to book tours offered by other tour operators.

Travel agents (also known as travel counselors or consultants) and travel agencies: Professionals with the expertise to analyze a traveler’s needs; recommend itineraries; and price, arrange, and sell one or more travel components (tours, cruises, lodging, flights, rail, car, guides, etc). Travel agents often have access to exclusive deals not available otherwise to the public. Zicasso strives to pre-screen and select travel agents with local knowledge of destinations as well as tours and cruises, adding value with their expert recommendations so you do less planning work.
