to the DISboards. How exciting, your first trip for your 7yr old
You can use WDW bus transporation to get to an early dining reservation from your resort. They generally start the buses approx. an hour & sometimes as early as 90 minutes before park opening depending upon time of year. Best to double check with your resort front desk, they can advise you if the bus will be running early enough for your time. Get to your bus stop early, and if there are mutliple bus stops at your resort, I'd recommend walking to whereever the first bus stops. (again your resort front desk can help with this) because most likely you will find a line of other guests wanting to arrive early for rope drop ceremony.
Taking the earliest possible bus to Magic Kingdom, once at MK, it is a short walk to the Contemporary Resort where Chef Mickey is located. If you have at least 15 minutes to spare, you can opt to ride the RESORT monorail for a little traveling fun. The Contemporary Resort is the first stop, exit and you'll see the Chef Mickey sign exiting the monorail inside the resort. It's a fun way to go
You can always take a taxi if you're nervous about your arrival time but I think you'll be fine with WDW buses
When you make your reservation, they will want a CC to hold your reservation. Your card would only be charged $10 person if you don't cancel within the time frame they tell you or if you don't show up. You can use your dining credits to pay for your meal.
Being your first visit, may I make a suggestion? JMHO but Chef Mickey is a very special dining event for a first visit and if you can't get the first available bfast time slot, you may find yourself in Chef Mickey's during the opening of the Magic Kindgom. The opening ceremony is also an exciting thing to see for a first visit and it starts about 15 minutes before official park opening. Mickey pulls up on a train and they "officially" open the magic kingdom.
You could try to book the latest possible bfast at Chef Mickey's, about 11:20 is around the last booking time, that way you can see the rope drop ceremony, enter Magic Kingdom and enjoy a few rides of your choice and see quite a bit in those first 90 minutes and then head over to Chef Mickey's for a later breakfast. Speaking from experience, they won't rush you out and you may find yourself getting lots of attention from the characters as the restaurant clears out. (Downside is you may not feel the buffet is quite as "fresh" as if you were first meal of the day)
Another suggestion since you're on dining plan, plan a DINNER at Chef Mickey's which averages about $10/more per person but on the dining plan, bfast & dinner are both one Table Service credit. Dinner starts as early as 5pm. You can enjoy the morning at MK, go back to your resort for an afternoon swim, and then go to Chef Mickey's for dinner before going back to MK for the evening.
One last suggestion, if you opt for dinner at Chef Mickey, inside the Magic Kingdom is the Crystal Palace, it is also on the dining plan, serves bfast, lunch & dinner. Granted you'd miss the opening cermemony, but if you book an early bfast at Crystal Palace, you get to enter Magic Kingdom EARLY and walk down Main St. before the general public, It's very cool to see the castle without a crowd of people around you, makes for great photos. If your reservation is an hour before park opens, you'll have plenty of time to eat and visit with Pooh and friends and then be leaving about the time the Magic kingdom opens to everyone else.
Have a wonderful trip
