Yeah Monsters was totally empty after the preshows both times I rode (twice around 10am and another two times around 6pm), and nearly a walk on to the preshow - a far cry from those early previews. It seems to have been pretty dead in general since Ministry went standby, though I wonder if getting more APs/locals in the park would help boost it up. While today was very light in terms of crowds, there was a clear divide between the waits for Nintendo/Potter (Yoshi aside) and the waits for Berk, DU and Celestial Park. Monsters, Werewolf, Hiccup's and Stardust were essentially "free" to get on throughout the day, while DK, MK and Ministry held respectable-to-long waits.
