Yes......however...that will be a challenge. WOC at 9 wraps at 9:20p ish. The first F! is usually at 9p ending 9:25p and Fireworks is at 9:30p so you have to fight upstream through the crows while the first F! is exiting and Fireworks is happening. Not an easy task and by time you get there they pack in the sections lie sardines so seating options will be limited.
I have seen a lot of pizzed off folks arriving later and trying to find somewhere to sit even though they have a FastPass for a section
