There are several liveries that service the area. A livery service will bring you and your boats to the put-in and arrange to meet you at specific times and places. They usually know the average time involved for your trip. Depending on the amount of people, they will be there to meet you promptly. The drivers are also a good source of information on the conditions of the streams.
Weekends are always crowded.
Be warned that you may have to navigate around inexperienced canoeists that are sideways in the streams. There are always party-people on weekends with the usual noise. If you can do the trips during the week, it is usually much less crowded and quieter. Different liveries generally service different streams. Your car can be broken into relatively easily, since these spots are generally out of public sight.
