You can buy tickets from SOG if you are down there, you don't have to be staying there to get them (except the Stars and Stripes tickets, I think they're called). Or you can get them from your local MWR office or the Navy base MWR in Florida. Their used to be a link to them on the Mousesavers website, I'm not sure if there still is, but if you contact them they will email you their ticket prices.
