Change My Score!

The remaining six contestants must quickly bone up on Vegas facts and tourism tips as they prepare to be tour bus guides. Who frets over reading the voluminous notes and confides that it's been 10 years since reading a book? Which contestant confidently tells the Vegas visitors that "the Venetian Hotel is so romantic, it's like...you're in Spain." Who can't pronounce Bugsy Siegel's name? And who tries to change their score in the competition when offered the chance?
