During your trip, it is recommended to rent a car since most of the locations are spread out. Expect to spend around $250+ on car rental and gas. There may be public transportation options available, but these may not be as convenient or efficient.
If you have more time, consider visiting nearby attractions like the Huntington Library and Gardens or the Los Angeles County Arboretum and Botanic Garden. For foodies, check out the local food scene, including popular restaurants like The Boiling Crab and Porto's Bakery. If you have less time, consider skipping the Commerce Aquatics Center and spending more time at other locations.
