The “Waves of Honor” ticket offer has also been made at other SeaWorld sites and related waterparks.

“We greatly appreciate the service and sacrifice of our military veterans and retirees, and have recognized them, along with our active duty military members, prior to the start of our killer whale show every day for the past several years,” said Marilyn Hannes, SeaWorld’s park president.

“This year, we are again expressing our appreciation further by offering veterans free admission, and we’re delighted to be able to extend the timeframe of the offer through the end of the year. Our hope is they will share an enjoyable visit to the park with families and friends.”

Veterans must register at Waves of Honor in advance, and verify their proof of service through the ID.me qualification process.

SeaWorld works with ID.me to provide an online verification of former military personnel in a secure and privacy-enhancing manner. Once veterans and their guests have registered online, they can bring their e-tickets directly to the park’s entrance turnstiles.

“I think Waves of Honor is a great idea,” said retired Marine Corps Sgt. Maj. Jay Lott. “I went online to prove that I was a veteran and got my tickets. It was real easy.”

Tickets must be obtained and redeemed by Dec. 31, 2016. This offer is available online only.

SeaWorld has paid tribute to active duty service members through a complimentary ticket programs for the military since 2003 with more than 2 million members of the U.S. and allied armed forces and their families having visited the park for free.

SeaWorld has also offered a number of complimentary and discounted admission programs to veterans in the last 12 years, as well as complimentary offers to teachers and emergency first responders.
