Are LSAC Forums Useful?

I have a business trip coming up the week after the New York LSAC forum. It turns out that its only $20.00 more expensive to leave the Friday before my Monday meeting and spend Saturday and Sunday in New York attending the LSAC forum. This would still necessitate cab fees and of course a hotel for two nights. Are these worth it? Also, would going to the one in New York, even though I'm primarily interested in West Coast +DC schools be worth it, or would the LA forum be better, even though I'd have to pay for the whole trip?
