Hi, Orinda!
You picked a great restaurant for breakfast! There's one easy route from
Disney's Coronado Springs Resort to
Disney's Contemporary Resort, home of the delicious
Chef Mickey's.
Grab a bus from Coronado Springs to the
Magic Kingdom. From the Kingdom bus stop, you'll have an easy ten-minute (or less) walk to the Contemporary, which will be in sight.
If the Magic Kingdom bus is crowded or lagging, your alternative is to catch a bus to any of the Parks, and from there, transfer to a bus bound for the Contemporary.
The most direct way, of course. is to drive; if you do not plan on using a car while you are at
Walt Disney World, and you don't want to take a bus that morning, taxis are plentiful at every Resort. If one is not immediately available, your concierge or a Bell Services Cast Member would be glad to help you out.
Because I'm an overplanner, I'll recommend you give yourself 40 minutes to an hour. This will allow you wiggle room to account for bus issues. traffic, etc.
Have a wonderful time dining with the Fabulous Five!
See you later, celebrator,
