I humbly disagree; the bedroom can sleep two average-sized adults on the lower bunk and one in the upper bunk. So if everyone's comfortable with such intimate quarters, there should be no reason it isn't allowed. If the issue is that Amtrak doesn't want to give complimentary meals to the third pax, there should perhaps be a separate accommodation type on their ticket that indicates "NO MEALS" (and the dining car stewards would know that there can't be 3 meal tickets for 3 adults from the same room).
