This is in partially caused by the park restricting seat belts so only ride operators can release them, which causes a longer load/unload time.  Unlike Flying Unicorn which has two trains, "Woodstock Express" only has one.  Riders must be taller than 36 in to ride with an adult and 48 in tall to ride alone.  "Woodstock Express".

Wooden roller coaster: A wooden roller coaster is most often classified as a roller coaster with running rails made of flattened steel strips mounted on laminated wooden track.  Occasionally, the support structure may be made out of a steel lattice or truss, but the ride remains classified as a wooden roller coaster due to the track design.  Because of the limits of wood, wooden roller coasters, in general, do not have inversions (when the coaster goes upside down), steep drops, or extremely banked turns (overbanked turns).  However, there are exceptions; the defunct Son of Beast at Kings Island had a 214 ft drop and originally had a 90 ft loop until the end of the 2006 season, although the loop had steel supports.  Other special cases are Hades 360 at Mount Olympus Water and Theme Park in Wisconsin Dells, Wisconsin.  The coaster features a double-track tunnel, a corkscrew, and a 90-degree banked turn.  There is also The Voyage at Holiday World (an example of a wooden roller coaster with a steel structure for supports) featuring three separate 90-degree banked turns.  Ravine Flyer II at Waldameer Park has a 90-degree banked turn, T Express at Everland in South Korea with a 77-degree drop, and Outlaw Run at Silver Dollar City which has 3 inversions and 120-degree overbanked turn.
