Attending BookExpo 2011? Good for Aspiring Author?

My writing partner and I are trying to decide if we should attend BookExpo 2011 and we need to decide it quickly since it's happening next week and we live in LA. We just found out about this event through our publishing research, hence the rush. We have completed our first novel, have started on the second in the series of three and are actively pursuing publication, in addition to considering the idea of self-publishing, if all else fails. The genre is Sci-Fi/Fantasy. This is not a new venture for us; it's a project that's been it the works many years. A few years back we did the whole submission-slush pile-rejection thing and it's very disheartening. Now with digital media and online publishing more of an option, we're giving it another go, and came across BookExpo. I would love to hear from anyone who could give me honest advice about whether this would be a good forum for us. We are attending ComiCon later this year, but we've done that before and the opportunities are limited. I'm thinking BookExpo is better for publishing, but not sure that it's so much for the Sci-Fi/Fantasy genre. Any informed help would be appreciated, particularly since this won't be cheap, with last minute airfare, staying in NY and the cost of admission.
