We're staying at the Hyatt Place right next to the airport, and have not rented a car. We'll Uber to South Beach today, and take the hotel shuttle to the airport in the morning. AA put us in a seedy motel 50 miles from the airport our first night; we're on our own dime now, and will argue with them about reimbursement later; no way I was staying there again. I understand that the venture card also has travel delay benefits. Right now all I care about is being comfortable and feeling safe.
