Whatever happens your jump is valid for one year from the date of purchase. So if you are not at the end of the validity of your jump, you have the possibility to return to a later date, of your choice, on one of the available dates.
On the other hand, if you already know for X reasons that you will not be able to return in case of cancellation, we advise you to take the cancellation insurance which is 10% of the price of your total reservation. This insurance allows you to request the refund of your booking in full.
As written on our terms of sale (put the direct link), if you request the refund of your reservation without having previously taken the cancellation insurance, a fee of 30 € are retained.
