When Lisa took the microphone on the deck below us (we stayed one deck above the pool deck) and enthusiastically welcomed everyone to the world's greatest deck party, we realized the group of young, good looking people behind her were the ship's dancers who had changed into casual clothes. Lisa started the dancing by encouraging everyone around her to follow her lead. Soon the whole side of the pool she was on was dancing in rhythm, clapping their hands and really getting into the spirit of the party. As more and more passengers joined in the dancing, more of the ship's dancers faded away, and soon, the whole pool deck was a mass of dancing passengers.
