Hey Kevin, I lived literally next door to Universal for about 10 months this past year and went there all the time.

HHNs is really fun, I would go, but one caveat.... The peak nights (as they are called) are jammed packed, as in filled to capacity packed. Lines are long, etc. If you can go, really aim for one of the non peak nights. If you have to go on a peak night, just pace yourself.

I'll be back in Orlando myself and going to it on the 16th. (A non-peak night)

Best place on the web I know for Universal/IOA Info is www.ioacentral.com (Unofficial, but very cool and I know the folks that run it)
