And different folks will have different perspectives regarding that. We never relax "by the pool", for example. We do relax on the train, though. It actually fosters relaxation (specifically) in a way that WDW can't. On the train, we are not able to pick up and go to the BoardWalk, or to Downtown Disney, etc. We are essentially forced to relax.I didn't say time at parks, I said time in WDW. Relaxing by the pool, Chef Mickey's, anything. Still better than spending 40 hrs on a train. JMHO.
And that's really critical. In the middle of the vacation it would be bad: After we've had a few days to relax and detach from "real" life we are better able to have fun - to really enjoy ourselves, doing things. However, at the start of a vacation, we're still burnt-out from working and the other obligations on our time. Similarly, at the end of a vacation, we realize that we need to "recover" from vacation and get ready to face the real world again. The train actually fits very well with the way our family needs to vacation.
We have to be traveling during those hours regardless. We leave on Saturday (really Friday evening, staying with family in New York overnight) so no one misses work.Your train may leave at 4pm but for us we'd have to leave early am to drive to Lorton, VA (missing a full day of school/work).
Time is valuable. The point is that spending it on the train is valuable for many people. And we were among those very surprised that that was true for us. We went into our first Auto Train trip ready to hate it and never do it again. We proved ourselves wrong.
