Orlando Informer holds after hours “meetups” at Universal a few times a year.
There’s one coming up in June (sold out), and then three weekends in November and December: 11/18-19, 12/3-4, and 12/9-10 (the last one is sold out).
Basically, you get to enter the parks at some point mid-day before they close to the public, and you then get to stay for roughly 5.5 hours after the parks close. There’s very limited capacity, so all rides are nearly walk-on and the parks feel very empty. The big draw is that (nearly) all of the Quick Service locations + food stands are open, and you can have as much food + (non-alcoholic) drink you want, all included in the price.
You want to try every flavor of ice cream at Fortescue’s? Go for it! Have as much frozen, cold, and hot Butterbeer as you want!
Tickets are roughly $200 for one night or $300 for both nights of the weekend.
OI also has exclusive rates on Universal Hotels, so you can stay at a Premier hotel for as low as $165/night.
Just Google “Orlando Informer Meetup” to find their website - I think it will block it if I post it here.
Happy to answer any questions you have!
