The "fanclub" has a 2 park/3 day ticket for $88.?? adults and $77.?? children right now, I'm buying mine on Friday. If you have the fanclub card, go to universalstudios.com/fanclub put in your 4 digits and you can look at the ticket deals.
It looks like the fan club rate for the five day pass is the same as the regular rate for the five day pass. I guess the three day pass is a two dollars cheaper, but not worth it if you are staying three nights, you can go to the park on arrival day for two dollars more. Oh well, maybe some new deals will come along.
