Family of seven, parents and five children ages 17 - 7 are planning a road trip originating in Seattle and ending up in SLC. This is a first for us!!!! (Americans living abroad!) Need advice please. Have seven days for driving. What are musts for us to see and what is realistic as far as driving times per day? Not so much interested in hiking, as seeing the beauty of the northwest. I was thinking of taking the coastal road 101 down to San Francisco and then over to Southern Utah and up to SLC. Is this too ambitious? Thank you for any assistance and ideas!
