My Mom used to take the auto train - roomette - and loved it! She arrived late rather than early for the departure so that her car would be one of the last cars loaded and one of the earlier cars off-loaded - that can take quite a while!
She also use to "brag" that she could get from Stuart, FL to Ocean County, NJ on just a couple tanks of gas!
