I have sat in all three sections with my family.
All areas are good and I would not stress over it in the least.
The upper balcony areas looks Down (you sit on stools that swivel and turn towards the show (over railing) and then eat turned opposite way! We've done this several times with no issues and it was fun as the "players" wander up there too and the big spot light goes on people up there too. We've had best wait staff up there actually.
We have sat on the floor, way in the back and it was the worst seating I thought . More because people ahead of us kept standing up constantly and blocking the view. It was a large group and the parents decided to throw all the kids (and some were LITTLE) together and all the adults at another table, nice right

so the kids would go over and moms and dads walked back and forth the whole night, so inconsiderate, even the wait staff said something. If it was not the standing it was the "i hope they're eating over and over!!! UGH!
We have sat on the mid floor area as well. ONCE we got very lucky, like right near center and it was great, another time we were too close up front and I felt like you craned your neck the whole night. It was still great fun.
Honestly though, where ever you sit you will have a great time (barring People and their issues) so Have a GREAT time..... It really is a fun time and YUMMY food too!
By the way, have the kids see the MK horses or animals, also in this area before the show. Give plenty of time for bus transport, takes 2 buses to get to location...
