Hello James! As of October 27th, Disney is expanding the dining reservation window back to 180 days. Since you are checking in on June 6, 2010, you'll be able to make your reservations as early as December 8, 2009!
The dining options at Walt Disney World are endless! You can research the restaurants online by visiting the
restaurants page. You'll notice there are filters on the left side of the page that you can use to help narrow down your search. For example, my guess is your children will enjoy the awesome character meals. You can use the filters by selecting "Dining Experience" and then "Character Dining." You'll be able to select character meals that you think your children will enjoy. One must-do, in my opinion, is Chef Mickey's!
When you're ready to make your reservations (on or after December 8th), you can do so online using the same restaurants page above or you can call 407-WDW-DINE.
Please let us know if you have follow-up questions! Diane :)
