How much should I save for olympics?

I really want to go to the 2014 winter olympics in sochi, so i figure i should start saving now. I just need a rough estimate. I would go to about 12 events and would like to be on the mountains near the snowboarding, skiing and bobsledding, but i might want to see the figure-skating and hockey as well. I know it is going to be expense. Thanks. :D
