The real bargain is taking kids on the train: Age 16 and under travels for 1/2 price. And it's great for parents in that no one arrives exhausted from driving.
Train seats are larger and more comfortable than those on planes, and you have two electrical outlets at every seat. You have space above your seat to store something like a medium-sized duffle bag, and larger storage space is available at the front of each car.
Two hints for anyone planning to ride the rails:
- Bring Clorox wipes. The bathrooms are beyond nasty. Related hint: Note where the train starts its daily trip. When the trip starts, they'll open just as many cars as they need for their initial passengers. As the train progresses, they'll "open" more and more cars. And a new car's bathroom will be clean. So if you don't mind moving to a new car, you can be first to use the facilities.
- Bring your own food. The food served in the cafe car is overpriced and just plain bad (though, admittedly, my food standards are fairly high: If I pay someone to cook my food, I expect it to be at least GOOD.). To give you an idea about what they sell: A frozen chicken sandwich or an individual pizza for $6-8. Or bags of chips, cheese crackers, or oatmeal cookies for $1-2. After my first train trip, I started bringing sandwiches and snacks, though I still buy cold sodas and ice (they sell alcohol on the train). I have heard that the full-fledged dining car is good, but I have no personal experience with that.
