I think the above reference was to the fact there are often two sessions at the same time you might want to attend, so by finding people with conflicts as well, you can trade notes after the sessions.
Yep, I guess I should have been more clear. I meant you can only attend one at a time.
There was a tip above about wearing your badge around the lobby - this is a great tip as it helps people find each other. If you see someone with a badge wandering around aimlessly looking for people - time to introduce yourself.
So even though I'm staying at the LV Hilton, should I hang out in the actual conference hotel after sessions just to find folks, or are they usually milling about in the general area of the conference center?
