Continuity mistake: A horde of policemen makes their way upstairs to the suite, and the inspector seizes the keycard and is about to open the door. He is having some troubles, and Theo points him where he has to slide the card. Once he points though, he moves his arm back. When the camera angle shows them through the open door, Theo is frozen in his pose with the arm stretched out still pointing at the lock. (01:28:50)
Continuity mistake: When Owen asks the concierge if he has seen the girl in the photo, the man is holding his hand on the microphone in the reverse shots and isn't in most of the front views. (01:26:15)
Other mistake: At the beginning of the trip we see close-ups of the passports of the three girls being stamped. The date is 19 Jun 2010. During the climax of the movie Emma's boyfriend puts a copy of "Le Parisien" on the counter, and the date there is Jun 10 2010. (00:12:00 - 01:26:20)
Continuity mistake: Realizing they are missing the necklace, the three girls get on the balcony looking for Riley and staring at the clock. When she says "At noon", Meg is leaning on the railing with the side of her hand, but her hand is in frame in the following shot, flat on the palm. (01:16:20)
Continuity mistake: Grace is in front of the horse stall after the polo match, closing the door. Her hand is still on the door when she is shot from the front, but both arms are hanging low in the intermediate view with the camera behind her. (01:00:00)
Continuity mistake: In the scene with Meg meeting Riley who just changed by the bikes on the promenade, the same couple of extras (woman with a cyclamen dress, a guy in a grey T-shirt carrying a blue towel) walks together when Meg knocks down the vespa, and then seconds later they appear in separate shots, still coming from the same direction as before. (00:46:00)
Continuity mistake: Meg loses her balance leaning into the Vespa by Riley. She hangs on to him with her hand on his upper arm, his shoulder and nowhere to be seen in the space of three cuts. (00:46:05)
Continuity mistake: Meg walks away from the other two on the beach. She reaches a step; there's a couple hanging out there. In the first shot the arm of the guy is on his lap, but seen from the front he has the hand on the step he is sitting on, and only then he raises it to his knee. (00:46:05)
Continuity mistake: On the beach, Emma makes a bit of a blunder with her "who died" comeback line, and awkward silence falls between the three girls. Grace turns around towards Meg who is leaving. The tip of Selena Gomez's ponytail flips above the shoulder when she turns; in the rest of the sequence some shots have her black hair above the shoulder, others no hair there, everything is behind her back. (00:45:25)
Factual error: Judging by what is shown at the end of the movie, Owen managed to install the new light switch while the lights were turned on. (01:40:50)
Continuity mistake: Theo spots Grace through the window grate and holds it with his left hand, right hand, left hand when he calls for her. (01:42:45)
Continuity mistake: The three girls are standing on the door of their hotel room. Emma has the hotel brochure in hand, held vertically. Grace slips past her and in this new shot Emma is holding the leaflet horizontally. (00:16:00)
Continuity mistake: The three girls spend the night in the hotel room drying the rain out. When Grace hangs up the phone and answers Meg, Meg's hair goes from the back to the front of her shoulder. (00:28:15)
Continuity mistake: Grace is whining to her mom about adding her new sister to the trip. Before she has to head to the hospital, her mom puts her hands on Grace's cheeks. At the cut, her hands are on the shoulders instead, and only then she moves them up to the face. (00:12:20)
Factual error: On the plane, Emma shows an issue of Hello! magazine featuring the heiress Grace is passing as. It's labeled as "number 1100, May 31 2010", but the May 31 2010 issue was actually number 1125. (00:30:30)
Continuity mistake: Right at the ending of the opening credits, Amanda is walking to the podium to deliver the graduation speech. Her robe is open in the faraway shot, then when she says "We made it!" her scarf is over the robe, more closed than before, then cut to a faraway shot again and it's all the way open again, and then it goes on with her robe full closed. But in the faraway shot when Meg makes her way across the gym, you can see the grey of the skirt again. (00:03:30)
Continuity mistake: In the dingy hotel room, Grace opens the window and spots the most stereotypical Frenchman ever soaking naked in his bathtub reading Le Monde. The newspaper in hand is folded differently at the cut. (00:17:00)
Continuity mistake: Grace gets the plate with the breakfast order, consisting of two eggs, two bunches of fries, 2 slices of bacon and 3 sausages. She rearranges them to serve them in a funny face pattern, supposedly, but one piece of sausage is missing, the fries are soaked in oil and eggs and bacon appear less cooked than before. (00:02:00)
