Was the parking detour as big a mess as it seemed? The way I go home from work, I pass just about every sign going towards Celebration and I4, and while most of them told you where to turn, I noticed the sign off the exit ramp from Osceola taking you south onto World drive did NOT say where to go. It just said "Studios Parking Detour" (or whatever it was). I myself even wondered, "Does that mean they stay in this lane and take the exit, or do they go straight to get onto World Drive?" Well, once I got near that blinking traffic light just off property, I realized that cars were SUPPOSED to go straight, because there was another sign there directing cars to turn right at the light, which would take them back to 192, and from there they'd get to the DHS main toll plaza.
However, before, when I was turning off of Osceola, I noticed a HUGE line of cars at that last light (the one right over the bridge above the McDonald's...imagine you were coming from DAK and going to any of the other three parks - THAT light). I couldn't even SEE the end of the line. I thought it was weird so many people would be coming from that direction, at first. My guess is that once people got off Osceola and the sign didn't direct them to change lanes to avoid taking that immediate exit ramp BACK onto Osceola, everyone just basically stayed in that lane and ended up making circle after continuous circle.
Even if they knew where they were going and got it right the first time, good grief, it was like a 20 minute detour!
