Taking Otay Lakes Road over to I-805 is mostly through a heavily built up area with lots of cross streets and traffic lights.
Perhaps if you got a late start every morning and went back to camp late in the evening it would be manageable.
I agree with this route from personal experience; I live right off the I-805 in Chula Vista. Northbound traffic is heavy in the mornings until about 9 AM, southbound heavy in the evening. Concerts at the amphitheater (currently "Sleep Train Amphitheater" but it has changed names often) can tie up the I-805 very badly. Also, construction on HOV lanes in the area is causing congestion and some ramps/exits are closed at inconvenient times.
One alternate route is to come toward CV from Pio Pico on Otay Lakes Road and then go onto the I-125 toll road (
