We are going to California in Nov. and I was wondering if anyone knows if Universal Studios offer any kind of dicount for a one day ticket or is there any where on line to get discounted tickets?
IIRC, there is a small discount through AAA. You can also get a discount by buying tickets in advance online.
ETA You can also buy a CityPass, which includes one day at Universal STudios. Depending on what else you were planning on doing, this might be a good deal for you. I believe the CityPass is 25% cheaper than buying all of the included admissions separately.
