Hey Jeff,
Why not a weekday, say 28, 29 or 30th of July (Mon, tues, or Wed). That is the week after IRI. Weekdays are not as crowded.
Why not just proclaim one or two of these days (unofficially) FIRST day at Cedar Point.
.
If people have to work during the week, perhaps they can make arrangements far in advance to have one of these days off.
We could arrange to meet a couple times during the day at certain places and times, just to say hi or join up with each other. We could even plan to have lunch together.
How about this.....everyone MUST wear their team shirts!
And HEY!!! don't forget to bring your coaches and engineers, too! Old people still love to ride the coasters!
