I'm not the least but upset by the loss of the parade. I'm far more worried about the other entertainment cuts.
The parade sucked up tons of resources (cast, crew, logistics, etc) and it was a one-time thing. If you left early, were busy—especially indoors somewhere, or just in the wrong place at the wrong time, you could miss it. Plus, I just generally think that the chaos it could cause on paths paired with not wanting to wait around for something to show up outside during a winter event just made it a middling offering at best.
I'd much rather see those staff, dollars, and effort go towards more path entertainment and/or atmospheric characters. I think offerings like that—things anyone can come across at any point in the night—probably result in more of the "special moments" an event like WinterFest should be attempting to create. That said, I worry that the cutting of other entertainment without replacement in addition to the parade is an unsettling sign...
