My 16 year old daughter wants to go to Cardiff in the summer after her GCSE exams with her best friend (also 16 year old girl, who mother said its okay for her to go), she purposes to get a bus from Gatwick airport to Cardiff central and stay in a hotel near by for Five nights. Both my daughter and her friend are mature for their age, their both sensible and have common sense but I'm just worried if they will be safe? She said their plans is to go shopping and look around Cardiff and they claim their not interested about going out in evening, I suggested London instead (which is close to us and she could stay with her older sister there) but she said she wants to go somewhere different, I just wanted some other peoples option on how I should approach the situation and anyone had any experience with this? What did you do?
