By coach (national express or similar) from our city to one around 100 miles away? We would see her onto the coach at our end and she would be met by older teenage cousins when she arrived. I've never used national express type coaches so no idea how safe it would be. DD is 13 and doesn't currently use public transport although we could do some local practice runs and see how she gets on. I actually think she would be fine but keep having 'am i being totally irresponsible to even consider this?' moments so need some objective opinions please
