Continuity mistake: When Neal and her daughter enter the presidential suite for the first time, Melissa puts the cut-out cardboard down and puts her hand down. In the next shot, she puts her hand down again.

Continuity mistake: While being held by the two kidnappers, both Neal and Mellissa go from being handcuffed together to being handcuffed individually, and then back to being handcuffed to each other once again.
Continuity mistake: While Neal is being held by the kids the floss that he is tied in changes between shots. Look at the shoulder.
