I just got Discovery Cove tickets through the online veterans offer... $189 for DC with dolphin swim (no other park admissions included).. showing $360 without discount for that day.
Just went thru this drill too. Thru the online "ID" deal the price for the day we wanted was $340 - details say 'from $****' and actual price was all over the map, variable by day. Going to the base ticket office I got the tickets for day we want at $220 per person and this
includes 14 days Sea World / Aquatica.
I used the ITT office at Patrick AFB which is in Melbourne Florida, on the coast about 1 hour from Sea World / Orlando. According to their web site they take phone orders and will FEDEX tickets (small fee) ....
