We arrive late Saturday night (as in 2 days from now!) in Vegas, and will be spending the night there. That means we'll be driving to Disneyland on Sunday.... and there's the problem. I understand that Sunday traffic from Vegas to Disneyland can be atrocious. What I'd love to get is a better understanding of the timing of the heavy return traffic. We were hoping to do Hoover Dam that morning, or some other small activity, before heading to Disney, but I'm questioning the wisdom of leaving Vegas later in the day. If we leave at noon on a Sunday, will we be ahead of most of the traffic? What about 2pm? In terms of arriving in Anaheim on a Sunday, is it better to take 210 to 57? Garmin GPS and iPhone maps both use 60 to 57, but I've seen a couple discussions that 210 is a better choice. This is our first DLR trip, and our first non-familiar-place trip in a very long time. I am totally stressed out, since I know absolutely nothing (other than all my research!) about where we're going. Any help would be most appreciated!
