...Dorney is in no way shape or form going to remove Hydra in order to put in a picnic pavilion.
No need to wait for any "source quote to get back to you. Common sense prevails.
There was also talk of relocating it within the park or sending it to another park that would take it. I personally don't know the geography of Dorney that well so I'm not sure where they could put it. Also, we need to remember, this park dumps a lot of money each year into maintenance, but they would make money every year with this new space. Also lets be real, the park is hardly ever crowded enough on the dry side to ever get real lines, but if they moved it to another park, they could market it as a brand new coaster and at a different park like MiA or Valleyfair, it'd be the best and most popular ride in the park and it'd actually draw a line, while saving those parks a ton of money over building a brand new coaster
