Best 5-days in Aug or Sep?

Hey everyone, I am planning a 5-day trip for my family who has been to WDW tons of times. However, this will be their first trip to DL. Which 5-days would be the best? The family generally loves shows and parades so seeing the unique DL stuff would be best - World of Color, fireworks, Paint the Night, Hyperion, Fantasmic (since I think it is so much better), etc. I was thinking 28AUG-1SEP however I’m not sure if I trust the Crowd Calendar prediction.

We are planning to go at this same time frame. The lowest predicted crowds are 28-31 so I am really hoping they are accurate :grin:
