i just wanted to update with my success today of upgrading to a power pass. I purchased 3 adult and 2 children (4 day park to park ) tickets. I bought them for working advantage through my union. I bought 1 week prior to the increase. I paid $170.99 and 160.99 respectively plus tax. Total was $924. Today was our 4th day in the park and I had to wait to upgrade till our last day because of black out dates. We only used 2 adult and 2 children's tickets (my Aunt couldn't come last minute). I went to guest services at IOA on our way out and got 4 power passes. They refunded me $63.90. . That's right they gave me money to trade into an annual pass. Freaking incredible.
