Yes. On the Caledonian Sleeper, the Classic and Club En-suite rooms both have twin bunk beds — one upper and one lower berth — so two people can share comfortably, while the flagship Caledonian Double has a genuine double bed for couples who'd rather sleep together. Rooms are always sold for sole use of that room, meaning you'll only ever share with your own travelling companion, never with a stranger. Because pricing is usually per room, two people sharing often pay only a modest supplement over the one-person price, so a cabin can be surprisingly good value as a pair. On the GWR Night Riviera to Cornwall, cabins are twin-berth compartments, so two can also share, again booked as sole occupancy. If you're travelling solo and want a room to yourself, you can book single occupancy on either service. Families should note the Caledonian Sleeper offers interconnecting Classic rooms so a group can be next to each other, and children aged four and under travel free (one per paying adult). The key points: yes, two can share; you won't be put in with strangers; and couples wanting a double bed rather than bunks should choose the Caledonian Double, the only true double on the Scottish service.
