Interested in the cold shower comments as both my recent journeys a few weeks ago I couldnt get the hot water to work. I had a cold shower on the way back to London after hiking all day as the showers were shut in FT lounge (COVID related no doubt, as were the lounge capacity limits).
I've used the Aberdeen sleeper before, so I was surprised at how bad the experience was, particularly on the way up where we were in an end berth and it was crazy noisy from some water tank and the alarm/comms system in the galley next door.
Breakfast was also much worse than I remember. Instant coffee bluergh.
Still better than flying, but I will be thinking hard before spending that amount again. It definitely felt like very poor value for money.
