To fully explore Inglewood, it's best to rent a car. Parking in the city is reasonably easy to access, and you will only require a short drive to reach all of the destinations on your itinerary. Alternatively, public transportation is available in the form of buses, but the routes may not be the most suitable for a tourist, but certainly a cost-effective alternative.
If you have more time to spend, you may want to consider adding a visit to the California Science Center, which has various exhibits that appeal to both children and adults. I would also suggest visiting the Venice Beach Boardwalk, famous for its street performers and street food. If you have less time, you may wish to skip certain attractions such as the Los Angeles County Museum of Art or the horse racing park, depending on your interests.
