I recommend the FP, unless you plan to eat in the park already. The dining plan is not required to have good seats and cut down on waiting. The FP provides great seats and allows you to enter ahead of standby.
We waited about 15 min in the fast pass line and were the first ones in the arena out of everyone. We sat front row directly next to the dining area. Here's some pics I took

This is the dining area on the other side of the rope. This was about 45 min before showtime.
