Use a travel agency that specializes in international trips. Agents have so many contacts and insider tips, they know exactly where the discounts are to be had.
Go online and search for group deals. There are several booking companies that will plan your group trip. Consider it a virtual travel agent. Enter your destination and watch as the website calculates your trip.
Get a package deal through a tour company. Such companies are headquartered in the U.S. and overseas. They offer a complete group trip to numerous countries and cities. It includes your travel, accommodations, tours and sometimes even meals.
Search for group discounts by using a website that specializes in comparing international flights. Airline Consolidator, for instance, has a database of more than 8 million flights to places like Africa, Asia, South and Central America, Middle East, Europe and the South Pacific.
Call hotels directly and explain that you're planning to book several rooms. Ask to speak to someone about group discounts. Most hotels offer this as an option, depending on how many rooms you're booking.
Reserve a bus to bring you around on tours. This is the easiest way for groups to travel while abroad. You don't want to worry about driving in a foreign country. Many tour companies offer the bus and a tour guide for a reasonable price.
