The book highlights the link between consumers and travellers, identifying the meaning of vulnerability in Brazil and the EU. It also covers different types of contracts for tourism and travel services, including online booking processes. Only after 2015, as a result of the directive on package travel and linked travel arrangements, did the EU begin viewing travellers as consumers in the sense of Union Consumer Law; conversely, in Brazil, the traveller has no legal status whatsoever and is considered solely a consumer. As the traveller is implicitly a consumer he/she is subject to vulnerability. However, the definition of vulnerability differs considerably between Brazil and the EU: while in Brazil it is a principle stemming from the Consumer Defence Code, covering all consumers, in the EU vulnerability is not an established principle.

In the EU, although the average consumer is assumed to be reasonably well informed, observant and circumspect, they are also recognised as the weaker party in the contract. That recognition does not fit with the notion of "confident consumer". Vulnerable consumers in the EU are those whose individual characteristics, such as their age, physical or mental infirmity, or credulity, make them particularly susceptible to unfair commercial practices. Conversely, in Brazil these consumers are seen as being hyper-vulnerable, rather than solely vulnerable. In this context, travellers are in a weaker position than regular consumers buying goods or services, because they are outside of their domicile or jurisdiction for a brief or extended period of time.

This book examines two types of traveller vulnerability that make travellers, particularly international ones, a special type of consumers: 1. External and 2. Legal (jurisdiction). Travellers’ vulnerability mainly stems from consumers travelling to different markets and different cultures. As such, they are subject to different laws that require special global attention.

While both the EU and Brazilian system have their respective advantages and disadvantages, the goal of both must be to further increase protection for travellers, including business travellers. In consumer societies, the traveller is indeed a consumer by logical causation and hence a “special consumer”.

本书强调了消费者和旅行者之间的联系，确定了巴西和欧盟的脆弱性的含义。它还涵盖了旅游和旅行服务的不同类型的合同，包括在线预订流程。只有在2015年之后，由于关于一揽子旅行和关联旅行安排的指令，欧盟才开始将旅行者视为联盟消费者法意义上的消费者；相反，在巴西，旅行者没有任何法律地位，只被视为消费者。由于旅行者是隐含的消费者，他/她会受到伤害。然而，巴西和欧盟对脆弱性的定义有很大的不同：在巴西，脆弱性是源于《消费者保护法》的一项原则，涵盖所有消费者，而在欧盟，脆弱性不是一项既定的原则。

在欧盟，尽管普通消费者被认为是相当知情、观察力强和谨慎的，但他们也被认为是合同中的弱势一方。这种认识与 "自信的消费者 "的概念不相符。在欧盟，弱势消费者是指那些个人特征，如年龄、身体或精神不健全或轻信，使他们特别容易受到不公平商业行为的影响。相反，在巴西，这些消费者被认为是高度脆弱的，而不仅仅是脆弱的。在这种情况下，旅行者比购买商品或服务的普通消费者处于弱势地位，因为他们在短暂或长时间内不在其住所或管辖区。

本书研究了使旅行者，特别是国际旅行者，成为特殊类型的消费者的两种类型的旅行者脆弱性：1.外部和2.法律（管辖）。法律（管辖）。旅行者的脆弱性主要来自于前往不同市场和不同文化的消费者。因此，他们受制于不同的法律，需要全球特别关注。

虽然欧盟和巴西的制度都有各自的优点和缺点，但两者的目标必须是进一步增加对旅行者的保护，包括商务旅行者。在消费社会中，根据逻辑因果关系，旅行者确实是一个消费者，因此是一个 "特殊消费者"。
