We are leaving in 2 weeks and I ALWAYS overpack, even though I don't intend to! I am from Louisiana where it is HOT AND HUMID and I hear the weather can be chilly along the coast and to pack in layers! We are staying in LaJolla and plan to visit the cove, LL, SW, Zoo and Coronado Island while in San Diego and then head to DLR! So I intend to bring a light jacket for each of us, to throw on if it gets cool, to wear with shorts from our daytime adventures. Maybe a pr of pants or capris for dinner. Is this enough? Thanks for all advice! It seems like it is warmer in Anaheim than in San Diego, just wondering if we would be cold if I just pack only shorts with lite sweaters or jackets? It just feels like I am going to bring half my closet AGAIN!
