cosi fan tutti with dd- which seats should I book?

[SSSandy]

Planning on taking dd (aged 6 years and 1 day) to the opera on Sunday (Cosi fan tutti) hopefully it goes well. Where would be the best place to sit with dc that age?

SeatingPlan

Price isn't so much the issue since it's a 4 pm family performance with dc under 16 paying 10Euros wherever they sit. She needs to be able to see but I'm not sure just how restless she'll be so probably shouldn't be taking THE best seats. What do you think?

Do you know if the seats in the stalls are sloped, raked or flat. I would be tempted to go for the yellow price band mid centre stalls with a child or yellow in what I assume is the circle (1st balcony)

If it was just me going I would go for green towards rear stalls or 2nd balcony. For opera with a child vision is very important but when I used to go to concerts I sat right at the top as the acoustics were great (specific to the particular concert hall I went to)

I imagine the ones at the very side might be sightlines

Oh, forgot, try and get an aisle seat of you can.

I was thinking about those yellow balcony seats too. Think that might be best. If we get someone really tall in front of both of us, she'll end up seeing next to nothing. The stall seats are sloped but not dramatically. Think we need to be in the front.

Thanks for your help!
