june vs july

[Zurgerific]

We're considering visiting June 6 through June 13 or holding off untill July.

Driving from New England down 95 in either case. Has anyone got opinions on the difference in traffic between the 2 times?

Is there a significant difference in the crowds at the parks between those 2 periods ? The official schedule would lead me to believe parks are less crowded before June 13th, based on park hours and spectromagic/fantasmic times.

We went in August last time and had a very trying time dealing with the crowd level . . . . .
