Yes, it was random when we went in June. The girls, 10 and 11, also preferred ST over MF, even though they were pilots on MF. MF was a walk on, in mid afternoon. They just had the four of us in the cockpit, which allowed for the girls to pilot. Some really nice lines for almost every day of our 10 day WDW trip. Slinky was the only attraction that always had a long line...and it broke down often during our three days at DHS.
