This was a tough one because they both have good and bad.
On the plus side of the early one, you will be in the park early for sure. You should be done eating by 9:45 so the park will be pretty empty. Plus, you couldn't do all that much before the meal anyhow.
On the flip side, maybe with the later one, as long as you would have been in the park at 9:00, you could have went and got a fast pass for Kali River Rapids and rode the Safari's before your meal. This is risky though because that can take awhile.
The best option is to get the latest breakfast you can on an EARLY ENTRY day. That gives you a ton of options, but it wasn't available for you.
If I were you, take the early ADR you made and get in the park by 8:00. This way you can take it all in and maybe they will get you in a little early.
When you are done, go get a fast pass for Safari's as soon as you are done. Then go do It's Tough to be a Bug, the animal trails and all the stuff in Dino land until your Fastpass is due. You could always just jump in line too for the safaris if the line happens to be bearable.
Have fun
