Have just survived a trip there with 28 7 & 8 year olds (helper on ds's class outing ) and ....it was brilliant
All the kids had a great time; lots of interactive things to do plus organised workshops - they got to make their own toothpaste - and the whole place was clean and well-organised. I would definitely recommend it. Plus the whole class was very well behaved, even if they did laugh at me when I fell asleep on the bus home .
