Its a perfect half day excursion with kids. My 7 year old daughter enjoyed it fully. Apart from seeing all European places, it gives lots of valuable information about places. My daughter loved volcano eruption model. You can easily spend half day there. There is cafeteria out there just before exit so you can rest and eat something before go out.
You can reach there by Tram / Cab. There is planetarium just outside it and that is also very good.
