Love me some F1 but went 2 years ago and it was a huge disorganized mess. Didn't help that it rained for 2 days before the race, which screwed all parking (mostly big dirt fields, not paved lots). Paid $100 for a premium parking spot close to the track which I was then denied from using, no refund. Then there was a huge amount of misinformation on the radio about parking at the downtown convention center and a shuttle will take you right to the track. Shuttles were running, yes, but hours long lines so "right to the track" was not happening. And yes you have to pay for parking at the convention center, never mind that you already paid for parking. Said to heck with that and parked at a grocery store on the east edge of town and called a taxi. Then after the event, no one knew where you were supposed to go for the Elton John concert, even the people that were working the event. Finally time to leave, guess what, no taxis allowed on COTA grounds (except for dropoffs), so had to walk several miles to a gas station to call a taxi. Glad I went, but probably won't be doing it again. Did I mention it was expensive as hell? Anyhow, you get more info from watching on TV.
