Nagaoka Matsuri 2024 Tips

My boyfriend and I will be trying our luck for Nagaoka Fireworks on 8/03 (Sat). Unfortunately we were not able to secure a ticket 😭

We will be going to Nagaoka by car.
Any tips on where to park?
Or where to see the fireworks given we do not have tickets?

Also, if you know where we can get tickets please tell me.
