My boyfriend and I are going on Liberty OS on May 9th. He is a deputy sheriff and recently received an email from his department regarding new discounts for LEOs and fire fighters. We were able to call the people we booked through and received a $150 refund... not even onboard credit (which surprised me!).
I figured this could help someone in our same situation. Look into it if it applies to you and maybe you can get some money back!!
