First, best wishes for the new year. What better way to start it than to find a job?
If you have helpful logistical information, or complaints or praise for the organization of the jobmarket, please feel free to share.
(E.g. logistical note: there are sky bridges connecting the Marriott to the Hyatt (on level AL of the Marriott) and the Marriott to the Hilton (on level ML), so you can pass dry between them...)
Look around when you arrive, so you can find where you need to go.
And if you hear any great talks, or if your interviews yield new insights, feel free to share that too--this will be a chance to talk about your work, and hear others talk about theirs, for an intense few days.
It can be stressful, but I hope you'll have some fun too.
