Three of my friends and myself are planning on taking a road trip next summer from Seattle to San Diego. We have three weeks to take the entire trip. The last 5 days we would like to spend in California (Disneyland, Universal Studios). I figure it will only take about 20 hours to get home if we switch off driving and take the I-5. On our way South we wanted to go through Texas, do you think this is realistic? I'm not sure if it is, as I have never driven that way before.
Thanks so much for any help or advice!
