Looks like they have to be used by march 26. I don't see anything past that date right now, although they could offer an extension to compete with the Disney offer.
I suggest checking with your ITT/MWR for their rates on tickets. We went Aug 2009. In Aug 2008 we started looking for tickets. I checked every MWR/ITT on the east coast to compare prices. While SOG was charging $100 for an adult ticket, I was able to get them in VA for less than $80 a piece. They were also willing to mail them to me for a flat fee of $15. Even with the mailing fee, it was still a huge savings for 5 tickets. Bonus came later when they offered the free military member ticket. Since my dad (who went with us) and husband are both retired military, we were left with 2 unused tickets that I have saved for our next trip.
Since you are a US newbie, also look into the military discount for the onsite hotels. You might have to call reservations for the discount amount as most codes don't work online. The savings is amazing and being onsite gives you unlimited FOTL which is soooooo worth it.[/QU If you are looking for a great place to try and fine a good place to stay you could try AFVclub.com. I have used them for the last four trips to Orlando. You can find places from 1 bedroom to 4 bedrooms that sleep up to

10 people. and they all cost the same. Less then $400 for 7 days. Made sure you use space A
