Military Salute ticket question. We are planning a June trip, it will be me, my husband, 2 kids, and FIL/MIL. Retired military FIL is planning on ordering our tix through SOG. We've just found out that he is scheduled for 8 weeks of daily radiation that ends the week before our trip. If there are unforseen circumstances preventing his going on the trip, are we just out of luck with these military tickets? If he buys the pre-activated tickets through SOG, including his own, will he still have to be present and enter the parks in order to allow the rest of us to do so? Obviously his health is most important but he is anxious about this trip working out so I wanted to make sure I can calm his worries with either A) the news that we can still use the tix if he can't go or B) that I already have a plan set in place if we can't (i.e. different tickets).
