Advice spans the gamut, from dining recommendations to transportation tips to entertainment suggestions. If you're traveling abroad, a knowledgeable agent can even provide instruction concerning areas like dining etiquette, cultural customs, appropriate dress, weather, safety, vaccinations, and passports and travel visas. Again, seek out an agent who specializes in your destination, who has been there a number of times in the past. Otherwise, you'll learn nothing you couldn't get from Google.
The final notable benefit of booking through a travel agent is simplification. If you're booking group travel, complications and headaches can quickly arise from juggling everyone's information and credit card numbers. A travel agent can keep the group organized and make sure everyone ends up on the same flight and in the same hotel. Your agent can also help resolve issues you face on your travels. If you miss a flight or lose your luggage, your agent may be better equipped and more experienced to handle the situation.
So is a travel agent worth it? It depends what you value. If money is your main concern, maybe not. But if you want to save time, curtail complexity, and get an insider's perspective on making the most of your trip, a travel agent might be the difference between a relaxing vacation and another tedious chore.
