I'm the OP of this thread and I wanted to give an update: My Daughter and I had a great time celebrating our birthday at Universal! We wore our birthday buttons and received a "Happy Birthday!" from just about every Universal team member we saw. It was even announced over the loud speaker at Jurassic Park ride. Woody Woodpecker sang Happy Birthday to us in his own way! We didn't receive any Fast Pass perks because we already had passes. But, the best surprise of all for my Daughter was a huge surprise Birthday Balloon bouquet with candy waiting for her when we returned to our room at the Royal Pacific that night! She also received an oversized hand personalized birthday card signed by the Royal Pacific team members!
