Does universal have fireworks etc?
 

As above really. Are there any sort of fireworks or evening shows? Don’t find much info.

Yes, it does. See above.

Unfortunately, because of Universal's location, neither of the above shows are anywhere near as loud and spectacular as Disney's firework shows. Disney has the advantage of owning all the land miles around the parks so can put on bigger nighttime shows without fear of upsetting the neighbours.

There are no showtimes coming up for the celebration in Universal Studios. Is that to do with Mardi Gras or am I just missing it?

I guess they are slow at updating their website with the times.
