Oh, yeah, I'd take a ride over the dining hall six days of the week and twice on Saturday. But they gotta build that dining hall and fast - they're leaving money on the table. It should have appeared somewhere years ago.
In terms of expansion ride priority (not necessarily my preference), I think HtTyD needs a major ride most desperately and Mario needs it least. Between Potter and Monsters, I think Monsters needs expansion slightly more simply because Potter Paris is likely to be a bigger draw and the Circus will hopefully by a more substantial attraction then Monsters coaster.
