12. It's a Mad, Mad, Mad Hotel

Complete story — includes the ending

When Zack and Cody's football breaks a painting hung up in the hallway, they find an article hidden in the frame about a mobster's arrest in 1938, saying that he would be coming back to the hotel for his treasure. Desperate, Zack, Cody, Maddie, London, and Esteban all imagine what their life would be like if they found the treasure, despite London already being rich. They all search frantically for the treasure, but they end up breaking into the bank of Boston. In the end, the real treasure was Muriel, who had a fling with the mobster. Guest stars: Estelle Harris as Muriel, Adrian R'Mante as Esteban, Brian Stepanek as Arwin, Ashley Tisdale as Young Muriel Note: When Esteban is having his fantasy, the symbols on the workers shirt still have a "T" for Tipton.
