If you are coming to Oracle Open World in SF this year the following is the map you need to memorize.
It shows you how to get from Moscone (where you pick your tag) to the Hilton SF - where all the developer related sessions are being held.
As you can see google is actually showing you the long road - all you need is to go up 4th st, and turn left after you cross Market.
The sessions at the Hilton are part of the Oracle Develop track which is free to anyone with an Oracle Open World pass.
Wondering what is there to see there? check out this page.
