<human>: Give me a shortened version of the text

We had plans to stay at my friends sister's house but her daughter is sick so that is a no go.  Neither of us have been before so my question is; Does anyone have any experience going to the 500 that can give some helpful advice? We wanted to go Saturday to partake in the pregame celebrations so is there a place we can park that it will be safe to sleep in said car that will not be crazy expensive?  I am assuming anywhere that people can pay to sleep will be booked up, and I have no problem sleeping in my car.
<bot>: Place to crash for the Indy 500 fell through, need advice on cheap place to stay or cheap parking safe enough to sleep in the car...Also any other helpful advice to make the most out of the trip would be helpful, thank you
