Hey, Carlene! After taking a quick peek at the
November Magic Kingdom Calendar, I saw where the park opens at 9 a.m. on the day of your reservation. However, because you're staying at a Disney Resort, there are special buses that leave approximately 1/2 hour before the first seating of the parks' character breakfasts. The buses run approximately every 15-20 minutes and will probably have something like "Character Breakfast" on the bus' marquee. You'll need to verify with the bus driver exactly which park the bus is traveling to since there are character breakfasts in each of the four theme parks.
Since your ADR is at 8:10 a.m., I would plan on leaving ASM around 7:30 a.m. to allow plenty of time for travel as well as getting through the gate and walking to Cinderella Castle. Plus, they ask you to check in about 15 minutes prior to your ADR. You'll simply tell the cast members located at the MK gate that you have an ADR at CRT, and you may want to bring your confirmation number as well (just in case).
If you were traveling to any of the other three theme parks, it might be advantageous for you to drive your car. However, Disney resort transportation is actually more convenient to the Magic Kingdom since they drop you off so close to the gate. I hope this helps, and thanks for visiting me here on the Moms Panel.
Congratulations on getting a prized CRT reservation! Have a wonderful day and a magical vacation!
