Diethelm Travel acts as intermediary between the concerned airlines, hotels, transport operators and local tourist offices providing the services. Diethelm Travel is therefore not responsible for any loss, injury or damage sustained by the tourists, including those occurring outside the touring programs.  Additional expenses incurred due to delay, accidents, natural disaster, political actions and unrest must be borne by the tourists. Programs, prices, services and conditions are based on those valid at the time of printing and are therefore subject to change without advance notice before or during the tour. Participation in our tour implies the tourists' agreement to the above condition.
