Those searched online, the quality in Thailand is free and sweet, are those reliable?

Free travel means booking air tickets+hotels, not joining a group, and deciding how to play by yourself. Free travel in Thailand is generally a holiday to the island. For people who are not familiar with the destination, it is more reliable to choose a travel society and they all need to buy insurance. Let's take a look at flying pig, hornet's nest, Ctrip and Tuniu. I have worked in a travel agency for five or six years, and I am too familiar with these tours. Free travel in Thailand is very cheap. Of course, if the requirements for hotels are high, the budget will be high.
