So me and DD are going to a concert in London however we live about 2 hours from Dublin by train and so we will need to stay overnight. I was looking at premier inns and was wondering if I booked her room and was also staying at the same hotel could she stay in a room by herself. I know the policy is 16+ to book a room but don't know about staying in one. She'll be a couple months off 16 at this point by the way and already can be mistaken for 19 or over.
