I think that's the best solution.

It's also the first one you come to from Vegas on the 15, so if the traffic reports (or googlemaps) say it's clear, that's the one I'd take. Bottom line: you've got 4 choices to get between the 15 and the 57: the 210, 10, 60, and 91. Use your traffic reports or googlemaps and take the first clear one, I'd say.

We ended up taking the 91 to the 57 because I read the exit number to the 60 wrong but it seemed a fairly smooth ride. Thanks everyone for all the advice. It turned out mom (me!) was the more worried one.
