Travel agent (T.A): Hello, it’s Green Leaves travel agency. How can I help you?

An: Oh, hello. My name’s An. I call to ask for some information about your tours. I’m having some days off and I’m planning for my family holiday this summer. Can you give me some recommendations?

T.A: Yes, of course! Would you like domestic tours or international ones?

An: Domestic tours please!

T.A: Great choice! This summer our travel agency is launching a bunch of promotions to customers, particularly for the new ones. If you buy a package of ecotours, you will get a discount voucher of 25% for the next tour. The program will close soon so don’t miss the opportunity.

An: It sounds interesting, but sorry, I don’t know much about what an ecotour is and where these trips are to?

T.A: Well, ecotourism is more and more popular towards the enthusiastic travelers these days. It’s very environmentally friendly tourism. You can discover the natural landscapes and find out many things about the tourist attractions without hurting the environment. At the present, we have the tour to Ba Be Lake and one of the most beautiful volcanoes in ASEAN Countries – “Chư B’Luck” volcanic mountain. We also have tours to Hoi An ancient town, but unfortunately, it just ended its promotion last week. Both trips take 3 nights and 2 days for each.

An: Amazing! My brothers and cousins will be excited about this kind of tourism. So, could you give me more information about the accommodation and price that I can choose…..?
