Infant and party on the 4th

We are having a viewing party on the 4th with family and neighbors because our view of the fireworks is awesome! I have a 7 month old who is on a strict bedtime schedule. We’ve never really deviated from it but we also want to have some fun on the 4th! 99% of the time the baby goes to bed in an ideal sleep environment. I’m a bit nervous because our place is very small. Our neighborhood will be setting off a ton of fireworks all night and people will be over. Any suggestions? I’m nervous he will have a rough night from all of the noise.
