One day in southwest Germany

[KKAddict127]

Wow, been a very long time since I was active in this great community but I had to come back because I have a unique opportunity on my hands. In about three weeks I'll have a free day where I can head to pretty much any park between Belgium and Berlin. I figure this southwest Germany "corridor" of sorts of great parks is where I should head. I only have a portion of one day (have to be back in The Netherlands at the end of the day), so as much as I'd love to hit up Europa, Holiday Park, Tripsdrill, Klotten, and Phantasialand, I'll most likely need to pick one (MAYBE two if they're close). I'm mainly interested solely in the coasters, so I've been thinking I probably need to include Holiday Park in there. I've never been to any of these parks. And I need to use public transport, no car. Any thoughts or suggestions? Thanks!

^With those restraints (time and public transport only), it's going to be tough to hit more than one park. I would just go to Europa, hopefully (depending on what time you actually get there and what time you need to leave by) you can get all the credits at least? It's kind of doing a disservice to Europa to treat it like that, but if you have the chance to see the park you should!
