I did see a convertible one time. There was 4 of us so it was too small. As a matter of fact, that was the only car on the full size. They let us take an Aztec from the Emerald Aisle (after asking if we were EC members). If you are an Emerald Club member, if you see a larger car on the EA, I would ask if you can take it, I bet they would allow it. You actually are paying more for the full size than someone who booked intermediate with EA.
