What to do with the money?

We are going on a 10-day vacation with our 3 small kids. The flight is at 5am so we thought about driving to the airport ourselves and park it there. It ranges from $100-180 to leave it parked including transfer to the terminal.

My husband’s aunt recommended this Uber-service she uses and will drop us off and pick us up directly where we need to be and it’s comfortable. She offered to cover most of the cost, which is $300!

She gave us 250 and said we can decide whatever we like! Would you use the Uber or drive yourself?
