Just wanted to let you know the early morning ADR path can work. Get to the check in line for ADRs at the park early, so you can be one of the first groups seated, let your server know your plan (they see people doing this all the time, and if they know you're in a rush, they also know they won't need to stop by to check on how you're doing, which helps them out).
We did this in November at CRT, with an 8:05 reservation. We were the 2nd table seated that morning, finished eating and visiting the princesses in less than 45 minutes, and had time to hit the restrooms before heading to the internal rope (just past the Castle, in front of the carousel). Stay to the left side of that rope -- the cast members will lead you around the carousel and into the A&E line. We were in and out in 15 minutes!
