I've read some trip reports from other boards. It appears Universal Studios Hollywood can be done in a day. You'll need a full day to do everything. The park is currently offering a buy one day, get the rest of the year free promotion. It's like an annual pass for rest of the year, but with no benefits like free parking. You can also purchase the park's version of a Fast Pass for about $30 to $40 more than a one day's admission. If you want to be treated like royality, you can do the VIP tour for around $140. From what I heard, you have your own private tram, look around backstage areas, and walk around a working TV or movie set.
