This is kind of embarrassing to admit, but this is our fourth year in a row of going in June and i was just wondering the same thing
You would think by now I'd know. If you are willing to accept a guess I'd say early April....I'm pretty sure i remember making 90 day PS last year before I knew the actual park hours and scrambling to adjust when they finally came out.
We have gone in May and September but never in June. We will be there this year June 4-12. What are the crowds like then? We are used to line maximums of about 20 min. in the morning and evening hours.
