I was in Millett several days ago, and talked with a few people.
One thing that I did not realize for football, was that when you buy a parking pass for the West Millett parking lot, it is not just for West Millett, but includes both lots on Bonham Road; so when West Millett is full, you get turned away & sent to Bonham Road. You are never guaranteed a spot in West Millett, just a spot somewhere.
Also, season ticket holders can purchase guaranteed reserved spots in East Millett, North Millett, all of the lots surrounding Yager & The DISC, and Hannon Park.
Which brings us to single game tickets & parking. When single Home game tickets and parking go on sale next week, Miami has no way to necessarily know if someone buying game tickets and parking on-line is a Miami fan or an opponent (Cincinnati).
It is almost certain that UC fans will buy tickets and parking, with many of them showing up in West Millett at 8 am for the noon kickoff this year.
So, if you do not get to the West Millett lot early, you will likely get sent to Bonham Road.
