Yes, haven’t seen which dates qualify for the DVC. Not a long list Last year, didn’t see anything for dates we went in Sept & October
Believe It was sold out year we went that night. Was surprised to see it available on a trip in a trip in august. It was much more doable on other dates we went that year.
Generally, first nights for any event, at any park, can be a bit of a cluster with staff still settling into their roles.
Our first night visit was absolutely packed with those individuals promoting the event. One too many people thoughtlessly making unexpected dead

stops in inconvenient places ’taping’ on their phones. I realize people rely on the bloggers for info, follow a couple myself

. however, there increasingly seems to be more than few who aren’t considerate of guests around them In the parks.
IMO If you can pick another night, would likely be less crowded.
