A vacation package is for independent travelers who want the savings and convenience of buying pre-packaged arrangements. A vacation package includes two or more travel services (e.g. hotel, air fare, car rental, sightseeing etc.) that are bundled together and offered at a "package price." Travelers can choose pre-existing packages or they can customize their own arrangements. On the other hand, a tour is a pre-planned itinerary, often including a tour escort and travel with a group.
Buying a vacation package or a tour is usually more expensive than putting your own vacation together. Buying a vacation package or tour can save you up to 30%, depending on the time of year and where you are going, plus hours of work over putting the trip together yourself. Because tour operators and vacation packagers contract for hotel rooms, air fares and other travel services in bulk they are often able to negotiate better rates. These savings are passed on to the consumer.
A tour operator – or wholesaler – puts the raw ingredients of your vacation together. The tour operator packages items like hotel accommodations, air fare, transfers, meals, and/or sightseeing. These packages or tours are sold by travel agents (retailers) or sometimes by the tour operator itself directly to the public. Think of clothing: the manufacturer (tour operator) produces the item that is sold in the store (travel agent) or directly (online).
While some travel agents charge service fees, the same vacation package will not cost more whether or not you buy it from a travel agent. In fact some tour operators and wholesalers only work through travel agents, so using a travel agent may give you a wider choice of vacation options. And because travel agents have insider information, they can often help you get better prices and access to travel arrangements.
Internet travel agencies work with a limited number of suppliers and therefore do not necessarily have access to specials offered by other tour operators or travel agents.
