We've been once for the main part and then once for just the dinner magic show. Both were OK, but my kids have not asked to go back - and we live nearby. The 4D simulator and ropes course thingy are extra. Assuming you mean just the main attraction, we found it to be equivalent to a science museum in a large city. You can spend a couple hours, and then expect to spend more time and money doing the other extra cost things - ropes course, 4D ride and laser tag. I'd say if you have not done a large science museum, then it would be fun.
