You might want to check out this thread: http://http://www.disboards.com/showthread.php?t=2057838 I don't have personal experience with the military ticket offer, but it sounds like all tickets have to be activated at the same time. Each ticket holder has to show id and it's a one per person offer. If that's the case, you couldn't buy extra tickets to use at a later date.
Thank you. I hadn't seen this thread before. Having all members of the party present with ID's to activate at the same time seems to be a requirement to prevent folks from using back to back tickets. The memo that I had posted didn't clearly explain this rule.
Since the Stars and Stripes tickets are $312 for 10 days and $298 for five days, it looks like this "benefit" is only saving $14 for someone planning a longer trip.
