Just faxed my copy of HAL shares to benefit department. (Fax 206-270-6080) Did not give my address. Just proof of 100 stock shares. Home mailing address and brokerage account number BLACKED out. Have to give complete legal name, booking /reservation number, ship name and sailing date no later than 3 weeks prior to sail date.
Received answer within half an hour! OBC will be “credited to your onboard account upon embarkation “.
I was surprised to get a response so quick. Very easy.
