Here is a redacted copy of the email from HAL, cut and pasted, as you can clearly see, they require proof of six month ownership.
Dear XXXXXXXXX
Thank you for your request to have a shipboard credit applied to your reservation XXXXXX based on your status as a Carnival Stockholder. Holland America Line would be happy to process your request. However, in the proof of CCL shares that was received, the following information is missing:
-KINDLY SHARE A CLEAR PICTURE OF CARNIVAL CORP STATEMENT PROOF OF LAST SIX MONTH .
If you can please resend the proof of CCL shares, with all of the required information, we will gladly process the request for shipboard credit.
Please provide by fax, email or by mail with your complete legal name, reservation/booking number, ship and sailing date, along with proof of ownership of Carnival Corporation or Carnival plc shares (for example, photocopy of shareholder proxy card, a dividend tax voucher or a current brokerage or nominee statement with your current mailing address and your brokerage account number blacked out) no later than 3 weeks prior to your sail date to your travel agent or to the cruise line you have selected below.
(misc. verbiage removed for clarity)
We sincerely apologize for any inconvenience this may cause you, and we appreciate your patience and understanding during this process.
We are looking forward to welcoming you on board in the near future.
Kind Regards,
Mohammad Danish
