In our case, we have lots of sites all over the world, so getting everyone in the same place doing anything in mixed team (mix of sites) helps build relationships etc. The format is normally a whole day of stuff, pep talks, awards, games and then a free bar all evening, night and early am in a local night club, so people can get completely blatted.
