The tour operator has a right to cancel the trip,
The tour operator must inform the traveller about the cancellation as soon as possible.
The traveller may demand a new, similar trip at the price which he paid for the original package, if this would not occasion unreasonable costs or inconvenience to the tour operator. If the price of the substitute trip is lower than the price of the original trip, or if it does not comprise the services which were originally agreed, the price difference or that part of the price which corresponds to the services which are not included must be returned to the traveller.
