My home park would be PortAventura (even if Tibidabo is closer... I don't go there usually...)
Favourite coaster would be Dragon Khan, without any doubt, followed closely by Furius Baco! (I've read the spanish trip report, -wish I could have gone, but I was working... meh- and dunno, last time I rode Baco it was really smooth! failing a lot during day, but smooth!)
