Hi Tracey,
Great choice! Chef Mickey's is an absolute fantastic place for a family meal. Not only is the food delicious with a great selection, but it is such an upbeat and fun place to be.
Dining reservations can currently be made 90 days in advance, and guests staying at a Disney World resort can make up to ten days of reservations on the first day they can call in. Reservations can be made by calling 407-939-3463 or online at
www.disneyworld.com. i personally prefer the old-fashion way of calling and speaking to a very helpful Disney Cast Member.
The Disney restaurants are extremely popular and many tend to book quite early. Chef Mickey's is definitely one of the locations on this list and often books up almost immediately at the ninety day mark. I would suggest calling to get your reservation as close to the ninety day mark as possible.
You did not mention your exact travel dates, but it seems that your ninety day mark may have already passed. I would suggest calling immediately to see what is still available. Good luck!
