Continuity mistake: At the beach, when Kate's getting there, you can see her bra strap; the next shot, when she turns around, her shirt's covering it.
Continuity mistake: In the scene where John is climbing from his hotel room to Kates' room, they should be on the same side of the hall, since he is trying to climb from his window to hers. After he is caught, they obviously go into rooms on opposite sides of the hall.
Continuity mistake: In the gym, when the girls are fighting Kate gets smacked in the face with the volley ball and she falls down to the ground, but in the next shot she's standing behind the girls, then in the next overhead shot of the gym she's getting up.
