Back in May, we were able to get all 5 at once. We started at Pink and got Red last. Red always had the longest line so my advice would be to send another adult in Red's line and hit the other ones. You might be able to get all 4 by the time it is your turn for Red. We must have had really low crowds b/c we didn't even need to send someone to wait in line for DD. However, we barely had enough time to get Red before they had to leave.........
DD didn't even know who Power Rangers were, but when she saw they had girl ones, she wanted to meet them. Now, they are her favorite b/c each one made her pose like them for the picture.
