If I were able to go overnight, I wouldn't care... show up in Phoenix at 9-10pm, wake up wherever the next morning. There are advantages to train. I hate the cramped space on airplanes... I'm fat and tall, it's uncomfortable to say the least, irrespective of how you may feel in terms of discriminating against fat people. I've often chose to spend adjacent days driving half way across country instead of flying a few times.
