During the Olympics, if its in your city, prepare for a couple of weeks of partying, it's unbelievable & nobody seems to be at work for the whole time.
During the Sydney one's I was off for 2 or 3 weeks and I'd never seen the city so packed (and it probably never will have that many people again, well not until the next olympics whenever that may be, if ever)
And I don't mean anything about the actual sporting events, It's just an awesome atmosphere wherever you are, pleanty of free gigs and other events, Huge screen TV's everywhere.
The nightlife will never be the same in your life again so make the most of it.
The Australian media have been ripping Athens preparation since the last Olympics, and moreso in the last few months. I don't believe the media, and the only reason is cause Our media still hasn't got over the last olympics and they don't think anyone can ever top the success of the Sydney games, plus Australians are very particular when it comes to any sporting event.
Just Enjoy it whether you watch any of the sports or not
