There's a gorgeous 4 story rainforest, and you can see the whole rainforest
It was, however, an amazing trip, even with waiting for so long! The major downside was that Claude, the albino alligator, was injured and wasn't on display. The kids (and I) were really looking forward to seeing him, but apparently he made another alligator mad and the other guy bit him!
The planetarium show was a little disappointing, as it wound up being essentially an Imax movie about saving the planet rather than having much information about the solar system.
For a relatively small museum/aquarium/planetarium, it managed to easily fill a whole day, and children 6 and under are free, so it wasn't overly expensive.
