While in Rotterdam awaiting a cruise, we heard about this mini world. Didn't know what to expect, but wasn't expecting a HUGE miniature railroad. Once we entered, there is a small layout and big layout. The small layout wasn't all that interesting, but the large one....wow.
We stayed about 2 hours and each time we walked around, we saw something new. The detail is amazing and the fact it gets dark every 24 minutes to simulate 24 hours in a day is pretty awesome. Loved the way it gets sunset, dark, then sunrise.
We kept walking around, and walking around, seeing new little details each time we looked. Sometimes it mattered whether it was day or night in there. We really enjoyed our stay, and probably would have stayed longer had we not had other places to get to.
