Forces Discounts Brochure has all the good gen.
Top tip: bring your 1250 with you when you head off for your 2 weeks in Orlando this year - it cuts a lot of ice with Americans (brothers in arms etc), great conversation starter, plus it'll get you discounts virtually everywhere! All you have to do is ask.
NB: your 1250 will get you free entry for you and your family to all the Anheuser Busch parks - SeaWorld, Busch Gardens - plus you get to stand up and take a bow at the 'Heroes Salute' bit in the Shamu Stadium!
