Well, it depends on which
Free Dining in September you mean
If you mean right now, the catch is the only way to get it is with the Disney Visa card as listed on the Discounts section here on the DIS:
DISNEY VISA MAGIC YOUR WAY FREE DINING PACKAGE
Rates low as:
$63 per person per day for a family of four in a standard room at a select Disney Value Resort
Includes Complimentary Magic Your Way Dining
Travel Dates:
September 28 - October 11
November 9 - November 22
December 14 - December 20
Booking Code: QXZ
NOTE: You must use your Disney Visa to book this package. If you wish to upgrade to the Deluxe Dining Plan, the Booking Code is OXS. - Three night minimum required. Availability is limited and certain restrictions apply
If you mean Free Dining next year in September (2009), so far the catch is that you have to book it as a Bounceback by staying in a WDW resort prior to October 24, 2008, and booking it for stays next year between 8/23-10/8/09
before you check out.
Or if you're not at WDW to book a Bounceback, the catch is you have to wait until probably around next April (2009) when a
Free Dining offer comes out again to book ahead for September (2009). And then the catch with that is that they usually offer it to Disney Visa cardholders first, then offer it to the general public about 3 days later, so availability might not be all that great.
The final catch on FD is that you usually have to book it as a package, you have to pay rack rate (no discounts, thought this might be changing based on the Disney Visa offer above), everyone in your party has to be on the same package, and everyone has to purchase at least a one day ticket.
