We had an 8:15 ADR last Sunday. We were among the first guests to check in at the gate, and we didn't dawdle for pictures, and had pre-ordered our food, so we were amongst the first people to be seated for breakfast. We had plenty of time to take pictures around the restaurant while we waited for our food, and we didn't take long to eat breakfast. We did kinda stall a bit because I wasn't sure if they'd let us out into the park if we finished too early, but in retrospect, we should have left as soon as we were done. We had our first Mine Train ride at 8:42 and our second at 8:47. When we came off the second time, we witnessed the beginning of the RD horde coming around the corner near the Tea Cups and we took off for Peter Pan, though the CMs at the entrance told us we could probably run through the FP+ queue one more time (that's where they were letting the breakfast people go through) if we wanted to.
That's my long way of saying...with an 8:25 ADR you're still going to be let in as soon as they start admitting breakfast guests. I highly recommend pre-ordering (we did ours just the night before) because it cuts down on a lot of time. You'll have plenty of time to eat and get to A&E.
This happened in 2002 when we had an early ADR at MK . I remember the year because as we were waiting for the ride open, the CM asked if we had a camera. I clearly remember thinking 'it must be a new security measure post 9/11'. Never, expected to see Piglet, Eeyore, & Pooh come out in the honeypots! We got to ride the whole ride with a Pooh! We were lucky enough to be sprinkled with a whole honeypot of pixie dust!!
