Using award points, I've sent some family members in a sleeper car across the country. I warned them that Amtrak wasn't a luxury operation, and that some inconveniences were to be expected.

Sure enough, in their first night in the sleeper, the toilets in their car (including their private one) malfunctioned, requiring them to use the bathroom in the next rail car. This (not unreasonably) displeased them. The situation was fixed the next morning.

Since they did not get the "enjoyment" of a private restroom in their sleeper car for a night, is this something that Amtrak would provide some sort of compensation for? On the train, the only thing the employees can/will do is say they're sorry (and, as mentioned, fixed the problem the next morning when they could). If compensation is possible, I assume they could write to customer relations? And would the fact that they're on a reward ticket matter? Thanks for the advice.
