I included the additional cost of the express pass in my post. Also, I did say HP attractions were not included. For a random 3 day pass (not at Christmas), the cost is $200. If you add Express pass the price goes up to $310.Also, Universal's "fast passes" are more expensive on weekends and peak times. Plus, it does not include Harry Potter. I have a friend who spent the $80.00 each for her sons and when they got to the back, it wouldn't let them skip the HP line and that's why she bought them.
Right now however, Universal is offering a buy 2 day and get 1 day free. I did not include this in my pricing.
