Beyond its year-round offerings, Universal Orlando also hosts some of the best seasonal events in the theme park industry, and several of them are included with any regular admission (including annual passes). For those events that aren't – Rock the Universe and Halloween Horror Nights – you'll need to purchase a separate ticket, and daytime Universal Express passes (including those included with hotel rooms) won't be honored.

The easiest way to find out which of the below events affect crowds is to subscribe to TouringPlans.com and utilize our accurate Crowd Calendar.
