I’m driving from San Jose airport to Paso Robles. Is it faster to take 101, or go over to I5? Looks like I5 is longer but I would guess faster. I’m just not sure how much you then lose going east to I5 and then back west to Paso Robles.
This would depend on whether the OP was going straight to his hotel in Paso or going to the lake first. If going to the hotel first, definitely stay on 101. If going to the lake first before going to the room, then take your exit.
