The internet connection historically sucks at the convention center and you will just be setting yourself up for disappointment if you are planning to check emails in-between talks. Also, the time in between is the BEST part of the conference. That is your chance to grab some free pens, eat some chocolates, and register for multiple iPad 2 giveaways (and you could make a few connections with peers who probably share more in common with than your own family). Seriously, take the time to mingle and talk with people while you are there – your email will be waiting for you when you get to your hotel.
Bring a few challenges you don’t know how to solve with you (write them down in a simple 1 sentence structure). New concepts will be turned into applicable knowledge through the action of applying the new concept to something personal and tangible. Try to view the entire conference as a stimulus collection opportunity. Use the networking breaks to share your challenge with a peer and see if you can connect the dots and stimulate some new thinking about your challenge.
