You listed the parks with the best coasters in your original post, so I would say you answered your own question.
However, if you prefer wood coasters then Holiday World would seem to be a place to go. I haven't been there yet (Will on June 6), but Voyage seems to rank high on everybody's list. And Knoebels has my favorite wood coaster Phoenix.
Robb, I was going by his term "coaster trip" in my response. I took that as he wants to ride coasters mainly.
