I arrived late evening, about 11:30pm, to Hartford, CT. I got my rental car and drove straight to the hotel and because it was so late, I left the car with the valet. I walked to my meeting the following day. Once back at the hotel, it was time to head back to the airport to catch my fight. I gave my ticket to the valet. They ran off to get my car. It took at little longer than expect for them to return. They asked me if I remembered the color of my rental car. Not being sure, after all, it was late when I got the car, I said dark blue, I think. Off the valet folks went again to try to find my car. After about 15 fifteen, the valet can back with a manger from the hotel. They informed that they think that my car was stolen from the park lot in that they cannot find it. They were very sorry for my inconvienence and offered me cash money to paid for a taxi ride back to the airport. They would call the police and report the car as missing. I took their offer and took a taxi to the airport. I called the hotel from a layover on my way home. They told that they had found my rental car. It is was two spaces down from where it was supposed to be and it was white, not dark blue. They returned the rental car to the rental company.
