We stay close to where you are staying. Get into the entrance gate at West before 9 AM and you will go thru very quickly. Too many folks can't seem to get out of the pancake houses' before 9:30 AM, sitting there getting a belly full and sucking up coffee. Get to the most popular places early and it will make it much simpler. There will be some hassles with a Class "C" at pull offs. And don't schedule times to be somewhere in the park as there will be animal back-ups, etc. If you are in a rush, don't even bother going in! This is what we have seen for the last ten summers while staying in the area for about six weeks at a time.
