According to accounts of Arthur Tudor and Catherine of Aragon's wedding - Arthur was 15, she was 16. They had been married by proxy in 1499 - but weren't married by the rites of the church until 1501, when she arrived in England.
Testimony of witnesses at Catherine's later trial for divorce from Henry VIII described the Couple as escorted to their bedchamber, undressed, put to bed together and the curtains around the bed drawn, while the witnesses (male and female) waited the night in the room.
Arthur is described as having thrust his head out from between the curtains in the morning, asking for drink - and stating to the gentlemen in the room that he had "Spent the night in Spain, this being married is a thirsty business."
Catherine always denied any consummation of her marriage to Arthur. Saying to Henry in court, that he knew the truth of the matter.
Servants ALWAYS slept in same room as their master or mistress - the higher the rank of the master, the more servants. Edward VI had four servants who slept in his room, the same as his father, Henry VIII. The curtains around the bed provided the "privacy".
Witnesses to the consummation were considered necessary because of the international implications of the marriage. Just being the room was considered sufficient, however. There were also witnesses to the birth of an anticipated heir.
I would suspect that TV shows would show the process as it's more interesting to view than it is to just hear. BTW, TV shows are for entertainment, not education - just because it's on TV doesn't make it true. I mean look at the so-called reality shows - reality just means unscripted, it doens't mean unstaged.
