The delegates are free to cancel their registration at any time by sending an eeeemail to Japo Jussila. All delegates are strongly encouraged to focus fully on the task in hand while registering, in order to avoid extra work in relation to sorting out registration hassles.
The delegates been already registered for IAA Cruise 2017 can get a 50% refund in case of cancellation until 1.5.2017. After 1.5.2017 no registration fees are refunded. This rather rough approach is due the red tape by the cruise company and, sorry to say, is thus non-negotiable.
