DD(14) needs to travel from Birmingham to Manchester, she will be alone but being met off the coach the other end. It's the first time she will have done it on her own and she's a bit anxious about who she might end up sitting next to so I'm wondering whether we could book the seat next to her as well as her own so it stays unoccupied? Can't find anything on the website and also don't know whether this would be bad coach etiquette
