You can make Las Vegas to San Diego in about 5 hours, but the people who love this drive never do it in one straight shot. At around 330 miles on I-15, it is short enough to start after breakfast and long enough to earn a night somewhere memorable close to the park gates.

Aim to clear Las Vegas before the morning rush, or after it, never in it. Fill the tank on the edge of town where prices usually drop, set the playlist, and settle in for the first 157 miles to Barstow.
The headline stop on this route is Seven Magic Mountains. Leave real time for it; it sets the tone for the whole trip.
Barstow
Barstow sits about 157 miles in. It makes a good spot to stretch, eat something that is not from a gas station, and swap drivers.
Nearby, Mojave National Preserve detour from Baker is worth the short detour if the day is going well.
Temecula, the last stretch
Temecula sits about 268 miles in. It is the natural place to stop for the night: hotels are plentiful, rates beat the big-city ends of the route, and you wake up with the hardest miles already behind you.
Rolling into San Diego
The final 62 miles always go faster than you expect. Save a little energy for Temecula Valley wineries; it is a fitting finish.
By the end you will have seen Seven Magic Mountains, Mojave National Preserve detour from Baker and Temecula Valley wineries, and you will understand why this corridor is a classic.
When to go and how to pace it
One night is the sweet spot. Temecula, CA is where most people stay, so book ahead on summer weekends.
