When I travelled eus-ftw earlier this week, there were no labels on any seats in the aberdeen coach. This resulted in a certain amount of confusion because some of the seat numbering is a bit unclear. There were people who'd agreed to move from their allocated seats so others could sit together, and this resulted in some people sitting in seats which weren't theirs but no information as to whether they were reserved, say from Crewe onwards. The coach was quite full, with some people squashed together somewhat with strangers, and yet there were a couple of two-seat pairs and single seats empty. I had my eye on one of those pairs (as an alternative to my allotted seat facing someone else) and after they weren't taken at watford junction I decided to take a gamble and move to them, hoping no one would claim them at crewe or preston. I was lucky and no one did, although it doesn't aid attempts to get any sleep, knowing that you might have to vacate. And if anyone had boarded, they'd have had to go through the awkward process of prodding me and asking me to get out.
Why don't they put labels on the seats? It would avoid a lot of these problems and make everyone's journey a bit more relaxing and less prone to conflict.
At edinburgh there were no labels in the fort william coach either - but the 2+2 seating meant that the layout bore no resemblance to the plan I'd chosen my seat on when booking anyway. There were more people doing the transfer than I'd expected, and each of the table bays had at least two people in it.
That layout I didn't find very conducive to getting any more sleep. And it didn't have the dimmed lighting of the 'proper' seated coaches.
