Like baseline seating, corner seating on the lower level of The Palace is mostly forgettable. The ticket prices in these sections are the cheapest in the 100 level, but there are better seats in the upper level for even less money.
The most frustrating aspect about corner seating is how far the seats are from the floor. The row closest to the floor in these sections is labeled AA. But even those seats are set back from the floor and don't enjoy the same atmosphere as courtside seats or those at center court.
As a general rule, you'll want to avoid most seats with a double-letter row (e.g.: CC), The high ticket price seems excessive when you consider a high likelihood of basket obstructions and flat seating.
For the best experiences in this seating zone, consider the rows at the top of each section. You may be tempted to sit closer to the floor, but the numbered rows in these sections offer better elevation and quicker access to the concourse and its amenities.
