Keep an eye on the website. I think the tickets go on sale in January (but dont let that keep you from looking in December

if you missed them I would be sad).
We have often gone down for a game (one during each of the last two years) and have not had trouble getting tickets for a weekday/night game, but ones on the weekends can be hard to get without ending up in the "grass" seats.
( I just looked at last year's "special events" page on the disney website...and they have already updated it for 2006 where you can save it to your favorites and when a release date for the tickets comes about, it will be posted there with a link)
Good luck getting the seats you want! (but I think you will have no problem at Cracker Jack)
