that might be a lot of fun as a welcome activity, and the end would be the dinner with lots of margaritas-you could pair people up who you think would get along but don't know each other. Do something around the resort in case people are uncomfortable going out and about.
They did this on an episode of 90210 once, when Steve and Janet were getting married, it was really funny. If you have SOAPNet that episode should be on pretty soon.
