My son wants to go to an event at the O2 arena in March with a friend. They will be almost 17 but hotels are saying they can’t stay without an over 18 present. I even checked with St Christopher’s hostel and they’re the same, even with a room for 2. I know some of the premier Inns and travelodges are self check in, are they likely to get away with this? I phoned a couple of hotels but they’re said they will ask for ID.
