My family is moving to Houston from Seattle and we are leaving the last part of September to first week of October. I will be driving down with my mother in law, 4 year old son, and car nervous French Bulldog. I've read a few threads here with info on the best routes for a 600 mile day, but I don't think I can realistically expect that considering my passenger load. I will be doing most, if not all, the driving and plan to start around 10am, stop every 90 minutes for breaks, one longer lunch break, then arrive to our day's stopping point by dinner time. I would love to see some scenic areas, but want to be sure we also have access to clean, dog friendly hotels, stops for fresh/semi-fresh food choices, and gas stations. I would like to do this in 5-6 days max if possible, but still stay realistic. Any thoughts? This will be my first road trip, so any advice is greatly appreciated.
