I have been to this in 2002. Cant remember the price though only that we did do the Laser quest at then end but paid seperatley and wished we had got a joint icket on the way in!
If I remember correctly it had a couple of booths that you could sit in and feel the force of hurricane wind and and an earthquake. There was also a game in which a computer would tell you your 'actual age' after you input various things like do you smoke, eat red meat, excercise etc.
On my trip in July/Aug I probably will go again just because I cant remember that much and my DF has never been at all.
