Overall, no you won't be able to see all of Universal in that time span. There are 2 parks, the other being Islands Of Adventure. If you've never been here, you'd still enjoy what you get to see, and that is dependant on the season. If low attendance, you'll see more. Summer and holidays are awful, you spend a great deal of time in waiting lines. The price you quoted is not outrageous, the cost of getting into the park itself is high.
If this is a once in a lifetime visit, you'd enjoy it.
