For everyone staying off site, there is a rather nice towncar service called Uber. I use it all the time in Seattle. But basically you can request a towncar from your smartphone and it shows it on a map as its on it's way, plus gives you text when its nearby, when it will be there, etc. Also you can add a personal card + a business card and it will send you an email receipt for each trip. A little more pricey than a taxi but highly reliable.
