Totally forgot to ask how tall kiddo is! That will affect some of the rides she can go on, but there's only a few that require a taller height than some 6yos.
My grandson who's going next week *just* hit the height for Incredicoaster, but has been tall enough for the others for a while now... and to be fair, he's kind of our "shrimpy" kid-- he's just always been smaller than our other grandkids; the 5yo was the same height as the now-7yo until just recently.
We're thrilled that character meet-and-greets are back with hugging, so getting a hug from Mickey and Minnie is at the top of our to-do lists. (The grandson this time is less than excited about this, as he's timid around strangers, so I may be the only one hugging my favorite mice.)
I'd consider Big Thunder Mtn Railroad as your daughter's "starter" coaster, then you can see how much further that she wants to go-- if that's enough, or if she wants to try Splash for example.
We adore the Main Street Electrical Parade. There's a dining package for reserved seating, which is what we traditionally have done. (I've got arthritis in my hips, so sitting on the curb waiting sounds torturous to me, so we are willing to pay a bit more for that reserved seating.)
I'd consider getting
Genie+ each day for at least one member of your party so you can get the ride photos and the PhotoPass pictures. Those PhotoPass pics are about the only ones we get with all of us in the picture!
