Perhaps you can once again make a concert with a banquet, during which will be contests, prizes raffled off, congratulations to read, and then - dancing. But such a scenario is usually the case every year, changing only the music and leading. But in order to make the holiday truly memorable, you can apply imagination.
For example, arrange a thematic corporate party. Options for this set. The easiest - pirate party, during which all must come in costume, and the script can be consider as a search for the treasure chest. Contests can also be themed - climbing ropes, juggling bottles, bathing in a vat of water, etc. If possible, it is possible to organize this party on the ship.
Gangster party. Everything is simple - all dressed in the style of Chicago 30s - striped jackets with broad shoulders, dark shirt, bright neckties, silk purple socks for men, women in vintage dresses and hats at the entrance are strong guys in hats pulled down over his eyes, etc. Alcohol is poured into coffee and tea cups, and on the big screen broadcast continuously (without sound) the film "Some Like It Hot," "Once in America", etc.
Christmas at Hogwarts. The staff are dressed in the colors of four faculties - Griffindera, Slytherin, Hufflepuff, Ravenclaw, CEO dressed in the garb of Dumbledore, chief accountant turns into Severus Snape, well, as the one whose name you can not let them come to call the main competitor or tax inspector.
Whatever held corporate holiday, it is always a place for the dressed up Christmas trees, gifts, fun contests and songs.
