I was reading your Washington-Cleveland trip and I had the same trouble you had with the cab company not showing up, only for me I was in Savannah, Ga. A cab took me from the train station to my hotel. I asked the cab driver if she could pick me up 4 days from now. She said it was fine. I called her the night before and she said she would pick me up the next morning to take me to the train station. The next day she never showed up at the time we agreed on. Finally, 15 minutes later I had to call another cab to take me to the train station. I made it to the station and 5 minutes later the train showed up.
