Honestly, sometimes you can't just look at it in terms of money. If you take the train, sure its cheaper, but it's inconvenient as all hell, AND you have to rent a car while you are there. Same thing with taking a plane.
If you drive there yourself, you don't have to rent a car, and you can head back at your leisure, NOT when your tickets tell you to. And you can just throw your stuff in your car any way you want when you leave. On a train or plane, you gotta deal with packing up your stuff and dealing with security and whatnot.
Even though one option may be cheaper, what you save in money you may pay for in headache. Weigh out all options, not just cost.
