The Grinch has delivered more than 10,000 hand-written cards from the line’s fans and employees to crew onboard Carnival Cruise Line ships.

Operation Happy Holidays was kicked off by Carnival’s Brand Ambassador John Heald and promoted by the line’s personal vacation planners and on Carnival’s Facebook page, asking guests and employees to bring some holiday cheer by sending cards to the roughly 125 crew members on each of its 23 ships who are maintaining the vessels as the company prepares to resume service.

Even the kids from the Camp Carnival child education center at the company’s Miami headquarters got into the act, creating beautiful handmade cards for crew, according to a press release.

The Port of Galveston Police Department also showed their thanks and appreciation by submitting more than 500 cards. 

“This year’s holiday season is different and our most sincere thanks and appreciation to everyone who stepped up and made our crew feel special and are making their holidays brighter,” said Christine Duffy, Carnival’s president. “Operation Happy Holidays is a testament to our wonderful guests and employees who go to great lengths to remember our crew who are the secret behind our success.”
