Of all the annoying things that can happen at amusement parks, slow operations are particularly irritating. Bad operations can be found anywhere, but it seems to happen at some parks/rides more than others. In this thread, tell us where you think the worst park/ride operations are.
-Six Flags Great America had decent operations in 2013, but it seems like they took a nosedive in 2014. Even though they were running the maximum amount of trains, you'd think they were running only one train based on how often/much the line moved. There was one time when Goliath's line was at a standstill for 10 minutes straight.
-Diamondback at Kings Island had some very slow operations when I rode it back in June, which is surprising considering that most B&M hypers are people eaters. They were double-stacking trains about 75% of the time, and the other 25% they were dispatching shortly before the other train pulled into the brake run. Maybe it's due to the unnecessary seatbelts.
-The lines at Adventureland (Iowa) were pretty long because the park's coasters can only operate one train at a time. The one-train operations are partially forgivable because the ride ops were friendly and working as fast as they could, but it would be nice if they could have the ability to run more trains.
