16. Going For the Gold

Complete story — includes the ending

Arwin enters the Hotel Engineers' competition which is taking place at the Tipton. Zack and Cody find out that one of the competitors, Arwin's rival Irv Wheldon, is cheating, so they try to help Arwin win. When Arwin finds this out, he scolds them, insisting he would never stoop to Irv's level. Eventually, Irv gets his comeuppance when he faceplants during a showy stunt to the finish line, leaving Arwin to pass him and win. Meanwhile, in an attempt to prove she doesn't give up so easily, London opens her own store in the hotel and hires Maddie to be in it, but London keeps on insulting the guests and ruining business. London eventually blows up an ad Maddie made on Mr. Tipton's blimp, getting them a lot of customers and money. However, the gas costs for the blimp cost more than what they made, putting them back at square one. Guest star: Donna Pieroni as Woman, Craig Shaynak as Irv Wheldon, Brian Stepanek as Arwin
