Travel agents are required to have a broad knowledge of the world, especially popular travel destinations. When you are planning a leisure vacation, a travel agent can suggest locations that fit your travel wants and needs. For business travelers, travel agents can offer knowledge about locations for meetings and conferences and suggest must-do activities for leisure time. Additionally, a good travel agent can inform you about local laws, customs, climate, travel documentation and travel advisories that concern your destination. Travel agents constantly increase and refresh their knowledge through attending trade shows and workshops and taking trips to familiarize themselves with different locales.
