I remembered Puzzling World with affection from my first visit, 16 years ago. To my delight, when I visited again earlier this year, I found it just as amusing as an adult as I did as a child. The giant 3D maze (it includes bridges as well as a traditional flat maze) is good fun, and the illusions rooms are genuinely surprising.
My only quibble with the place is the price it's $15 to visit the maze and the illusion rooms, which is ok if there's only two of you but can get quite steep if there are more. Still, I think it is worth it, and it makes for a great way to pass a couple of hours.
