Popping to the shops in the daytime maybe 10yrs but I wouldn't be comfortable leaving a child under 15 in a hotel room unless I were downstairs in the same hotel. A whole evening at home then I would either try and get them to have a friend stay over so they had some company at 13/14. I just don't think younger children are equipped to deal with an emergency should it arise. Of course everyone will have a different opinion depending on their own experiences and the maturity of the children involved but I think most parents are a good judge of their own children.
