As mentioned in another post, we'll be in the area soon and I have always wanted to do one of those alpine slides/coasters!

I have done a little research and found these within driving distance: ALPSEE COASTER IMMENSTADT, OBERAMMERGAU ALPINE SLIDE, ALPSPITZBAHN NESSELWANG

Can anyone tell me which is the best of these or if there is one that is better that I missed? (We'll also be in Ortisei after Fussen if that's a better choice for doing these.)

Thanks!
