Yes, the orchestra seats are elevated some. But like most theaters, not enough that if you get a tall person in front of you you'll be able to see over them. The orchestra seats are offset from one row to the next so that you should be viewing between the shoulders of the 2 people slightly left and slightly right in front of you. You should be able to see this when you look at the seat map to buy your tickets.
We had Row 10, seats 11 and 12 and I liked the view for our ballet. One row back might be better for both of you to be directly in the center. Of course row choice is a matter of preference and from what angle and distance you want to view the performance.
