Beware -- sometimes at busy times they will seed the Intermediate aisle with Compact cars, so that they can put the true Intermediates on the Emerald Aisle.
When we were there for Spring Break, every car in the Intermediate aisle was a Kia Spectra. Not a bad little car, but definitely NOT an intermediate by US standards. At 177+ inches long, it's an inch shorter than a Toyota Corolla, and 3 inches shorter than a Chevy Cobalt.
A Pontiac G6, by contrast, is 189 inches long.
