Lily loves the playground at the University Mall so much that sometimes we go just to play - without any intention of shopping! This is a perfect rainy day or cold weather activity. They have a few things to play on (the tree house with the slide, the hollow log, a dinosaur skeleton head, body, and tail) which are all spread out so there is plenty of room to play. It's a perfect indoor playground for younger kids and toddlers.
Next to the playground is a moving ball in water. Lily loves to play with that too (as do the other kids). I definitely recommend trying out the University Mall indoor playground in Utah County if you haven't already. For a shopping center play place it's a pretty good one.
