Hi I am planning a trip from seattle to Las Vegas in late November early December, trying to figure out my best option. I was thinking to go I-5 to sacramento and into reno, looks like the weather and conditions may be sketchy and not comfortable driving mountain passes in the late fall. My second option which the map tool here and mapquest suggest going I-90 over snoqualmie pass down thru yakima to boise then twin falls and straight down on 93. I am fine with driving snoqualmie pass done it plenty and comfortable with the area and looking at the maps looks mostly low lands and no major passes after that. My concern with this route is 93 thru nevada how are the conditions and the access to gas lodging services on this route, also a little concerned for safety on that hwy. I am traveling with 3 children and my husband we can take either 2 or 3 days for the trip down and this route looks faster than I-5 over to reno. How are conditions in the southern Idaho area after we get thru yakima as well?
