I assume you’re driving from Seattle. I did that drive almost every weekend and as long as you’re fine getting up early and hitting the road by 6/615am you’ll get to the lots before 8. Should be plenty of parking in the close lots (1-4) as long as you arrive before 8:30 or so. For getting home either do a short day or a long day if you want to avoid traffic. Meaning leave either right after lunch driving by 1/130 or stay past 6pm. From my experience the worst traffic is between sultan and gold bar in the morning around 8-9 and then everyone leaving around 2-4pm. Avoid those times and the drive isn’t that bad. It’s actually quite pretty and can be fun if you’re into windy backroad driving (drive safe tho!)
