Each section has a varying number of rows and seats per row. If you already have tickets, find your seats for row and seat numbers.
As you face the field from your seats, lower number seats are on your right.
Blankets do not appear on the Citrus Bowl prohibited items list (available here). Although you will want to make sure that it will fit inside of a small bag (large bags/backpacks are not permitted), or be prepared to carry it in on its own.
All sections at Florida Citrus Bowl stadium will start with single lettered rows in the front, and followed by the double lettered rows towards the back of the section.
