Where did you get those shirts? I want those!
Also take into account the driving time in la a trip from calefornia science center to downtown (10 km) took me like 45 minutes when i where there
Else the trip looks awsome i would recommend buying a fast pass at universal studios line is 30-60 min per ride
Calefornia science center is way more than endeavour. They have 1:1 copies of cassini, viking, and many more plus real apolo, gemeni and mercury capsules plus they have many military planes including the blackbird so spend as much time there as possible
