You were thinking Six Flags: Worlds of Adventure - the merger of an existing park and a Sea World.... Cedar Point's parent company, Cedar Fair, currently owns it and it's a waterpark now.They also own King's Island and Carowinds (and the other former Paramount parks). Hard Rock/Freedom Music Park is now dead. Knights of White Satin was said to be the best dark ride made to date. Sorry I missed it.... As for the Harry Potter park, it's actually a section of Universal's Islands of Adventure park, and jam-packed to the gills.
So did they take the coasters out? I know there was a waterpark too when I was there but it was a small part of the park as a whole. As for Knights of White Satin, I think it was the best attraction in the park because 1) it was air conditioned and 2) it was unique. They had the insides painted all crazy and gave you some glasses that made the walls move and stuff, while of course playing the song. The park as a whole was doomed to fail. The location was bad, the price was too high and the park was too small. You could go on every ride and see every show in about 3 hours if you planned it right.
I'm not sure I have a favorite park really. I do like the ambiance of the Disney parks but they lack a good variety of good coasters. Cedar Point has great coasters but I've never been there at an off peak time so I've always had to fight the lines. I waited 3 hours to ride Millennium Force shortly after it first came out.
As far a coasters go Space Mountain at Disneyland Paris is my favorite but I haven't been on it in a long time. Typically though, as long as its steel I'm happy. I have a bad back and I can't handle all the rattling on a wood coaster, although Son of Beast is one of my favorite coasters and its wood, mostly.
