Usually we make a stop overnight on the way down & back, but are considering driving straight through this time...at least on the way down. Any tips from those of you who make the trip without overnight stops? Your schedule? When you leave? Any info would be great, as I just don't know if this is for us or not. We will be leaving from Southwest Washington with no little ones.
Thanks!!
I've driven this stretch probably 5 times round-trip without stopping overnight, so I totally understand the drive. I find that I like arriving in the late afternoon, so since we're around 24 hours away (we live in Vancouver, BC), we usually leave around 4pm-ish, then stop in Everett for dinner, then continue on. That way, we have time to get settled in, have dinner, relax and have a full night's sleep before hitting the parks bright and early the next morning.
I find that if we leave in the morning, we're both usually exhausted by the evening and one of us has to drive. The other reason we like leaving a little later is because we can 1) Sleep in the morning of our drive 2) We have time to get everything together and 3) Traffic is usually lighter.
I'm not sure if you're taking the 99 or the 5 (probably the 5, I'm guessing) but we have places we like to stop for food/gas and/or a small break. Grant's Pass, Corning, Buttonwillow and the exit right before you head up the Grapevine for In & Out.
My biggest tips would be - pack snacks & drinks (more than you think you'll need!

- we drink iced tea by the gallons, so I always make a ton before we go) and also, we listen to audiobooks. We try to find ones that are interesting AND funny, like those by Sarah Vowell, David Sedaris, etc. Your local library may have them on CD, or you can get them through iTunes as well. We also like listening to standup comedy (we have satellite radio, so we just listen to that) as that keeps us awake!
