If your family is of four, then s/he is given 2 rooms at most of the destinations around the world. As per the safety norms, 4 Guests are not allowed in one hotel room, all over the world still there are hotels that have options for Family room or an Apartment Category with them, but this totally depends on the Hotel and as per the destination.
