We JUST got back from a trip to Disney/hollywood. My daughter's birthday was on the 31st and we took her there since we were staying in Burbank.
We did Universal for 2 days cuz right now they have a ticket that we paid 49 online for and got a second day free. Good deal when you consider 1 day I think is 61 at the gate. Anyway then we went to the Hollywood and Highland center and toured the Kodak theater which is where they have the Oscars. My little ones weren't that impressed but my teen loved it as did we and it only lasts a half hour so the little ones were cool with it. And of course there is Grauman's chinese where you can check out the stars as well as the walk of fame and we went to El Cap and saw Santa Clause three. They had a holiday show with the characters before the movie and I heard that they usually have some kind of thing before but you might want to call ahead.
We did the VIP seats which got us reserved balcony seats a bucket of popcorn in a souvenier bucket and a soda. They were 24 bucks and if we hadn't gone during a holiday I probably wouldn't have paid that. As it turned out there was hardly anyone there either. So as long as you aren't going during a peak time I would just pay general admission.
Then after the movie the El Cap is connected to the soda fountain where we went and celebrated Katy's birthday. They have a couple of sundaes that come with a limited edition pin if you are into pins and they have some other neat stuff.
There is also the usual tours of stars homes and there are other studios you can tour like NBC, Warner Bros and Paramount. My kids are 6, 7 and 14 and had a good time.
Let me know if there is anything else you want to know. I have pics too of the El Cap and the soda fountain as well as the Hollywood and Highland area.
