This is one huge park. You simply cannot visit all the sights in one day. Pick what's most important to you and enjoy it. We spent an entire day at the California Academy of Sciences and came back another day to see the rest of the sights and stll didn't have enough time. So my advice is to take your time and choose your favorite place(s) to visit.
