If you're heading to JavaOne 2011 you might as well take advantage of some discounts while you're in San Francisco. Although the tourism website is still sporting last year's conference banner it seems that the discount deals for JavaOne and Oracle OpenWorld attendees are valid until the 31st December 2011 (unless otherwise stated).
Just remember to take your conference badge with you while having a look around the city.
JavaOne is being held in San Francisco, 2nd-6th October, 2011. If you want to find out more about JavaOne 2011, check out the official website, or follow the news on Twitter: @javaoneconf.
