Corrected entry: In the beginning of the film, Vivian, (whose face we haven't seen yet) colors in her boots with a black marker held in her right hand. Near the end of the film, as Vivian is getting ready to leave the hotel and she's signing the papers, she uses her left hand. Julia Roberts is, in fact, left handed, as opposed to the stand-in used in the initial shot.

Correction: Quick google check says she's left-handed not ambidextrous. This entry shouldn't be corrected.
Whether Julia Roberts is left-handed is irrelevant. Her character could still be ambidextrous.
Correction: Julia Roberts is left-handed but its quite possible for Vivian to be ambidextrous.
