Thanks Icena! I intend to have a blast
Also thanks for the info, I knew about the stars but I have a feeling that parkgoers will be able to get a glimpse of them at least. They're very polite and always treat their fans with gratitude in public, but who knows how it will go down! I'm just wondering if anyone else here is going to go! We're definitely camping out Thursday night.

Here's the information I could find, keep in mind this is not confirmed however.

Stars who will be there:
Daniel Radcliffe
James and Oliver Phelps
Rupert Grint
Tom Felton
Bonnie Wright
Warwick Davis
In addition it's reported the composer of the films, John Williams, will be at the grand opening with a full choir and orchestra.

Celebrities who won't be there:
Helena Bonham Carter
Gary Oldman

Theme Park site Behind the Thrills is reporting that guests will not be allowed into the area where the grand opening ceremonies are taking place. There are large screens set up in front of the park and near Three Broomsticks in the Wizarding World. So if you go, you may not get to see the stars in person.

The media events begin on Wednesday and run through Friday. Some of the events, will be open to the public. While other events during the three days may be private. It’s possible some celebrities could be at one event and not others. Major media from all over the world are expected to attend. NBC’s Today Show will be broadcasting live Friday morning.

If I were you, I would arrive sometime in the middle of the night or the day before to get in line as I assume it will be packed.

I really wanted to! However I live in London, so no such luck, haha.
I hope you have lots of fun and see stuff with your favourite character on, haha! (Useless information: Lupin is my fave, lol.)

i'm going to be there and i was wondering if any other collectors are? i'm a huuuuge harry potter fan and i'm not really sure what to expect on this day! it's june 18th in orlando, florida at universal studios
