What a blast it must be for the artists and engineers to work on this project! I've seen large model train exhibits that were pretty boring -- I mean after you look at the exhibit and watch the train go around, you've seen it all. This exhibit looks really amazing. The computerized effects really are spectacular.
I just visited their website. The exhibit is only 12 euros which is currently $15 and some change. Quite affordable and they have food you can get while you're there. They also have annual passes, which might be a good idea since the exhibit is always changing and it's so big you can't possibly see it all in one day.
This almost makes me wish I lived in Europe, so I could go see it. My bucket list includes seeing the Terracotta Warriors in China (I saw an exhibit of them in DC a couple of years ago ... it was a small exhibit but still really amazing), I think Wunderland will have to go on my list now too.
Thanks for posting.
