Hi, Jerry!
Wow, your family must all be early birds to have a 7am
Chef Mickey's breakfast reservation! Just make sure that everyone has an early bedtime the night before so everyone is happy to wake up on time!.
I would stop by your lobby concierge at Coronado Springs the day before and ask them how to ensure a taxi will be available for hire at 6:30am, or if they have any
bus service they can offer you to get you to
Disney's Contemporary Resort for your 7am reservation. Many guests will have the same question, so they will be happy to instruct you. If you do choose taxi service, this will be your quickest option with wonderful door-to-door service. It will probably cost about $20-$25 dollars, so make sure to plan that in your budget.
After breakfast, you can take the lovely walk over to the Magic Kingdom, take the
monorail to the TTC to transfer to the Epcot line, or take a bus to Disney's Hollywood Studios or Disney's Animal Kingdom. You will certainly have the whole day ahead of you to fill with magic!
Have a super time at breakfast and please say "HI" to Mickey and his Pals for me!
Cathy
