My son is almost 17 and wants to go to see the UFC at the O2 arena in March with a friend. We live in the south of Scotland and he hasn’t been to London. He’s sensible but I’m worried about him being in London on his own. They would get the train down on the day, go to the show then have to stay in a hotel. Hotels close are very expensive. If I let him go he would need to get on the tube at North Grenwich which is the jubilee line. Any ideas as to best place to stay. I would want the hotel to be close to a tube stop. Not sure if I should be worried about him going to London!
