From a The Italian Eye Magazine online review:
Blindfold Travel offers a complete package with flights and overnight stays in a European city. The customer is only asked to choose the budget and fill out a questionnaire to indicate wishes and preferences. Blindfold Travel organises your holiday from the starting point to the end by providing all the useful information to travellers, who reach the airport completely unaware of their destination. Before leaving, a package containing the various directions arrives at home, and a series of numbered envelopes guide you step by step to the discovery of the journey as in a treasure hunt.
The only important elements to know are the departure date, time and some hints about what to bring with you; but it’s only shortly before leaving that boarding passes are sent by email. The surprises continue with other offers already included in the package, such as guided tours, museum tickets and many other activities. If you are already curious and want to find out more, you will be amazed!
