3 Days in San Diego Itinerary – What to See and Do
"Start the day in Balboa Park and try to get there early because this park is HUGE (and by huge I mean there is a freeway and several other roads running through it). Balboa park isn’t just green space, its packed with the best of San Diego’s museums and you’ll want to do some pre-planning to decide which museums you want to see in the time available (half a day). I’m a space and science nerd so I made a beeline for the Air and Space Museum."
