I find Discovery World to be rather expensive (abt. $16.95 for an adult) and we would not have done it but we had an Entertainment coupon that helped to curve the expense. On the day we visited they had local art vendors so it was interesting to see the items for sale as well as the attractions of Discovery World. Since my first visit, they added a few more things, but my kids enjoyed the water area with the ship and then, and mostly, the hamster wheel. It was enjoyable, but probably won't visit for many years to come. I've been at other interactive museums in the States that I found to be a lot more interesting and fun then the Discovery Museum (and cheaper).
