I was planning to travel to LA for a trip of around 4 days. I am planning to spend time in LA on 24, drive down to San Diego on 25th and then maybe drive down for a day trip to Las Vegas on 26th. Come back to LA and then drive back to the SF area the next day. I will be travelling with a toddler and wanted to get a feel from the experts (i.e. you all :)) on whether this trip sounds realistic? especially the day trip to Las Vegas? Any suggestion on what to keep in mind, the road conditions this time of the year and the general description of how the highway between LA to Vegas is and how long it may take me to get to Las Vegas and back to LA would be helpful and much appreciated.
