Cancellation costs

4. Cancellation before the holiday begins and cancellation costs:
a) The customer may withdraw from the holiday at any time before the holiday starts. Cancellation must be sent to Best-BikeTours, to the address specified below. If the holiday was booked via a travel agent, cancellation can be sent to this agent. We recommend making the cancellation in writing.
b) If the customer withdraws before the holiday starts, or does not start the holiday, Best-BikeTours loses the right to claim the travel price. Instead, Best-BikeTours can demand suitable compensation for the travel arrangements and expenses in proportion to the respective travel price, except in cases of force majeure. When calculating the compensation, saved expenses and any possible other uses of the services are taken into account. The compensation is calculated as follows after receipt of the cancellation:

for boat & bike tours is the compensation:

Up to 84 days before the start of the holiday 10 %
83 days – 42 days before the start of the holiday 30 %
41 days – 28 days before the start of the holiday 60 %
27 days – 04 day before the start of the holiday 80 %
03 days – day of arrival/no-show 90 %

for cruises is the compensation:

Up to 30 days before the start of the holiday 20 %
29 days – 22 days before the start of the holiday 50 %
21 days – 1 day before the start of the holiday 75 %
day of arrival/no-show 90 %

c) In all cases, it is the responsibility of the customer to prove that the damage caused is actually smaller or non-existent than is stated in the fixed sum of reimbursement.
d) Best-BikeTours is reserved the right to demand a higher, concrete amount of compensation instead of the previously mentioned fixed sum. In this case, Best-BikeTours is obliged to provide concrete evidence for considerably higher expenses, taking into account saved expenses and any other use of the travel services.
e) The statutory right of the customer as per § 651 b of the German Civil Code (transfer of the agreement) to suggest a replacement participant remains unaffected.
