Hello and welcome to the Disney Parks Moms Panel!
You have chosen two very MAGICAL Disney dining experiences.
Chef Mickey's and
The Crystal Palace are at the top of my "must do" list with every Walt Disney World vacation. I love these two dining experiences and I am quite sure they will become a family favorite for you, too.
On my last visit to WDW, I spoke to a Cast Member concerning this very matter. Although it is highly recommended that you call (407)WDW-DINE and try to change your party number, restaurants are very accommodating when it comes to folks showing up with one or two additional quests. Now with that being said, please understand that restaurants do reserve the right to turn your additional guests away, but it is very unlikely.
Diane's Tip of the Day: If you are a fan of character dining, I highly recommend
The Garden Grill which is located inside Epcot. There is nothing better than dining with Chip 'n"Dale! Trust me!
Have a MAGICAL day and "SEE YOU REAL SOON!"
Diane G.
