Very glad you find the panel helpful.
So, you have an 8:00 am Advanced Dining Reservation (ADR) at Cinderella's Royal Table
(CRT)? Sounds like you've been planning well! Are you sure this is your first trip with the kids?? ;-)
The best way to get to CRT at the Magic Kingdom is by bus, because it will drop you off near the park entrance. If you drive, you'll need to park at the TTC, then take a tram to the Monorail, and then take the monorail (or the boat) to the Magic Kingdom.
Buses for character breakfasts at the Magic Kingdom typically start running as early as 6:30 am each day. Click
HERE to read a prior post with more details about the buses for character breakfast meals. You should be fine catching the bus at around 7:15 am (others might say 7:30, but I like to play it safe).
Typically you will be able to enter the Magic Kingdom starting at around 7:45 am, and will have plenty of time to take a few photos as you stroll on over to Cindy's place for breakfast.
