If chosen, you will be
responsible for your own travel arrangements as well as any overnight accommodations, which are often needed in order to report for duty on time and remain aboard until all duties are complete and you are dismissed by the captain.
Keep in mind that
volunteers report for duty earlier than the trainee boarding time, and remain on board after the trainees disembark. If you are offered a position, your specific volunteer times will be outlined in your trip assignment email.
