Hi. I booked a family room for myself and my 3 children for a one night stay in London. We are on a really tight budget so I was very happy with the room I found for the price. Now my mum wants to come too, but the hotel is fully booked on our date and there are no other hotels with room available close by. I wondered if anyone had sneaked an extra person in, and if it was worth considering. The online booking stated we were 2 adults and 2 children, so now it would look as if my 5 year old is the extra. We have no problems about sharing a bed for one night, just unsure if there are strident checks...?
