I went last year and I can honestly say I had a good experience at the fair. I am registered to attend this year as well. The only thing that is somewhat weird is that you will be interviewing in hotel room suites. Typically you will interview at a table in the "living room" section of the employers' hotel room. If you can get past that, you should be good. Overall, I definitely say sign up and attend. Last year I had an interview that I didn't even sign up for so those opportunities exist as well.
