As you face the field from your seats, lower number seats are on your right.
For Redskins games, Section 306 is a part of the Club Level, featuring wider, more comfortable seats, in-seat wait service, and access to the climate controlled club level lounges which have upscale restaurants, bars, premium furniture and multiple TV monitors.
The seats will not have any overhead cover, but from the second tier of the stadium these seats will have a very good viewing height to the field and no sight line obstructions. You will be on the side closest to the Redskins bench which is good for home team fans, and viewing will be from just behind the west endzone.
With the good viewing height and comforts of the Club level, these seats are an excellent choice for Washington Redskins games.
Section 328 at Fedex Field is a part of the Zone D Club on Fedex Field's Club Level. These tickets will permit you access to all of the restaurants, lounges and bars available on the exclusive 300 level. If you prefer to not leave your seats, you can instead take advantage of in-seat wait service.
Row 15 is about halfway up the section, so you'll be about 6 steps from the concourse and all of its amenities. To access your seats initially, you can use one of the elevators near section 101 or 122.
