The parade is usually on the morning of the 4th. Pretty early too. Best viewing spot is right out front of the meadows trading post. There are a bunch of activities thought the week leading up to the 4th. And after the parade everyone meets by the beach to see who won best cart!
Here is last year's page 2 of the Movies & Activities sheet that is included in the check-in materials everyone receives leading up to the 4th. It lists the special things and details on the parade that you asked about.
Of course, last year's list is no guarantee that this year's list will be identical but it might be something you can at least generally plan with. Plus there are videos on youTube of past parades and they are shot right in front of the Meadow Trading Post.

PS - and mouse14, that's funny that everyone goes to see who won after.
