My charter week starts within 2 months – but I am reluctant to make a payment- while we cannot predict how will the situation look like?

You have two options: the first option is to make the payment, and then, if the situation doesn't look right, you can cancel even a day before (for the above-mentioned reasons) your charter starts and still use the whole voucher amount.

But if the payment is not received according to the contracted conditions – we will have to cancel the booking and keep the whole amount without issuing the voucher.
