Daytona ticket options for my first NASCAR race!!

Looking for opinions on my plan for 3 days of Daytona with 3 people. Still haven't bought my tickets, but thinking of doing the following to gain some experience:

- FanZone for the Duels.
- General Admission for the ARCA/XFinity races.
- Assigned seating for the Cup Series race.

What do I not want to miss?

Advice on parking would also be appreciated. I'll be staying south of the track in the Cocoa Beach area.
