Looking at the seating plan, there are two sections marked 'A' at the front, on either side of the stage. These sections are designated for wheelchairs. Each 'A' section has 4 wheelchair symbols.
Total wheelchair seats = $4 + 4 = 8$ seats.

First, count the total number of standard seats.
There are 10 rows of seats, labeled B through K.
Each row has two blocks of seats, with 10 seats in each block (10 on the left, 10 on the right).
Seats per row = $10 + 10 = 20$ seats.
Total standard seats = $10 \text{ rows} \times 20 \text{ seats/row} = 200$ seats.
Now, subtract the wheelchair positions from the total standard seats.
Seats excluding wheelchair positions = $200 - 8 = 192$ seats.
