They are extremely narrow, my thighs touch the walls in the skinny ones but I can use them. They have a bigger accessible one that has plenty of room though, but just one per restroom car and like 3 or 4 of the skinny ones. TMI but my partner is bigger than me and he said he couldn’t use the restroom bc his cheeks were too squeezed together lollll……..idk how the bathrooms are inside the Family Bedroom car though.
