Thanks Macraven - lots of good advice. That Sunday is our next-to-last day there, and we have only one HHN planned, so we have to make the most of it.
The last time I was at HHN was 2002, "Islands of Fear", when it was held at IOA. I remember that it was a lot of walking, and I also remember how totally creepy it was in Jurassic park (terrified of dinosaurs, to start). I do not believe they had the EP or SnS then, but they did offer the Frequent Scream pass for $19.95. Pretty sure our tickets - for a Saturday night - were $29.95 I still have the map from that one.
I do remember getting into the first house fairly quickly, but by the time we hit the fourth one the lines were immense. A couple of guys told us later that night that they went to the left from the entrance, through the Marvel area, and worked clockwise through the houses, which were scattered all over IOA. They were able to get through five of six without waiting much from that strategy since most people naturally move right and go counter-clockwise.
One thing to mention to those who've never been: it's easy to get dis-oriented in the parks at night, but especially IOA, with the circular layout and little paths everywhere. I am glad it's at the Studios for that reason alone.
I will definitely take you up on your tour guide offer. I don't yet know if we'll do SnS or EP - it will be one or the other, but if we could hook up with you any help will be appreciated . . .
