The Internet may have become your go-to source for planning a vacation, but savvy travelers head to a travel agent when they want to save time and money. “Why spend four weeks planning a four-day vacation, when you could call a professional agent at no additional cost?” says Michelle Fee of Cruise Planners in Coral Springs, Fla. Why indeed? Agents are paid by hotels, cruise lines and other travel suppliers they book you with, so few of them charge anything for their services. Because they sell a ton of trips, cruises and tours (an estimated $100 billion in 2013), travel agents receive special deals or amenities such as room upgrades, airfares or spa credits, which they can pass along to you. Even if you are working with a travel agent who charges you a fee, you can save enough on a complicated trip to more than offset the fee.
