My father is coming with us on our next trip and wants to get his own room. He served in the Vietnam War but was discharged after that. My sister believes if he just books a room with the military discount and pays in advance he won't have any problems upon arrival. He doesn't have a military I.d. - which is why I foresee a problem. Anyone have any experience/knowledge with millitary discounts? I do not want my father starting a Disney vacation with a problem. Thanks for any help.
