Nick Parker: You two help Meredith.
Meredith Blake: Sure you'll help me. Right over a cliff, you'll help me.
Hallie Parker: Not a bad idea.
Annie James: Yeah, see any cliffs?
When Hallie trashes Annie's cabin and the huge water balloon is about to fall on Annie's head, the camera is at a downward view and Annie clearly steps into the trail of the balloon instead of jumping away.
As Hal meets Meredith coming out of an elevator in the hotel, she is mumbling "Let's Get Together", which was a song from the original movie.
