We are going down for a short trip 4/3-4/9 and we are purchasing the Armed Forces Salute tickets w/t park hopper and water parks and more options. My question is when do these tickets actually expire, normal tickets expire 14 days after its first use. Since we are down for 5 full days and the tickets are for 4 days..ect..I just didn't want to get a rude surprise on our 5th day and possibly miss a day at a park. THANKS!!
