(16)In order to increase clarity for travellers and enable them to make informed choices as to the different types of travel arrangements on offer, traders should be required to state clearly and prominently whether they are offering a package or a linked travel arrangement, and provide information on the corresponding level of protection, before the traveller agrees to pay. A trader's declaration as to the legal nature of the travel product being marketed should correspond to the true legal nature of the product concerned. The relevant enforcement authorities should intervene where traders do not provide accurate information to travellers.
