Continuity mistake: When the pupils are boarding the coach the weather is dry and sunny, but as soon as the coach drives off the ground is wet and the weather dull.
Visible crew/equipment: When Mr Baxter is in the phone box, you can see the camera reflected in the glass as the door closes.
Audio problem: When Mr Baxter comes into the coach after contacting the holiday company, Miss Lexington tells him it was worth a try, to which he replies,"Yes it was." We then cut to the pupils who are seen cheering, yet no words are heard.
