In late August me and my family (Wife and two boys, 16 and 15) will be driving from Palm Desert (following a two week stay) to the Grand Canyon Southern Rim. Then the next day we do GC to LV and the day after that LV to LAX, so I have a lot of driving to day. Mad I know.
Anyway, specifically on the PD to GC drive, we'll be taking the most direct route which I believe is I-10 to the 62, 95 and then I-40 (suggestions welcome if this isn't the best way). My question is are there regular places to stop to stretch our legs and visit the washroom if necessary on the way? I haven't driven long distances in the US for about 20 years, way before having a family, and I realise that the particular route we've chosen is very much across country. For that reason I want to make sure that there's regular places to stop along the way.
Any help or tips you can offer will be greatfully received.
