Visible crew/equipment: When Michael is street dancing towards the end of the episode, about 5-10 seconds into the routine (as he's shuffling his feet on the floor) look just above the table on the right hand side of the screen. You can easily see a camera crew behind the table.
Factual error: At the pool party at the end of the episode, Asa Elliott is singing Gold by Spandau Ballet. Whilst he's singing, the shots change to different couples/families at the party. When Asa finishes the song, 5 minutes and 58 seconds have passed. The actual song is only 3 minutes 55 seconds.
