Hannah's recommendation! You must check out the penguin house and get Dippin' Dots.
Free to enter! Paid parking and extra exhibits.
The City Museum was one of Maya's favorite places growing up. Very family-friendly and catered to kids a lot of the time, but adults enjoy it too! (Especially if you have a childlike sense of wonder). Basically, a rich guy built a giant metal indoor/outdoor playground, which also includes a circus, an art center, caves, slides, and lots of things to climb. Everything is very colorful and whimsical.
Free to enter! A science museum with a cool planetarium. Maya used to work here :)
