My wife and two teenage daughters are taking an Alaskan cruise from anchorage to Vancouver in early August. I was told taking the train was very scenic, but if didn't know how far I should take it. Our end destination is San Francisco. We have roughly 7-9 days for the journey to San Fran. I have never taken a train before so I don't know how it all works regarding getting on/off. I would like to get off at certain spots and get on a day or two later. If someone could explain the benefits and drawbacks, that would be helpful. For example, will we miss too much by taking a train rather than driving? We would love to see the sites, and stop at key spots to get out and get close to some things. Any help would be appreciated.
