We visited to watch a special show on the Fragile Planet. We didn't realize until arriving that the price of admission is good for only one planetarium show. For the price, I think unlimited shows would be appropriate. The show itself was alright but rather superficial and focused more on the appropriateness of Earth for life relative to other planets rather than its fragility. Following the show was an enthusiastic live explanation of what would be seen later that day in the night sky which I enjoyed more.
