I have two opinions I would like to share.
1) I think is would be awesome to have the same event hosted at different times in one day. It makes it easier for everyone to have a chance to participate.
2) I also think it would be nice to extend events past an hour long. There have been a few time where I sit on the queue for the entire time. Then the event ends and all I get is a get a tiny prize. Meanwhile, during that hour I am unable to play mini-games because I am holding a fastpass. I have seen many players get annoyed because the "consolation prize" is a mere 250 credits. It's very upsetting.
