I find that PP has a shortish line for about the first 30 minutes ( at 30 minutes after park opening it was at 20-25 minute) I think the inside part of PP is fun it is cool since it is inside. how ever I find SM has a shorter line longer but latter in the day it can be about an hour+ and same with PP SM has some interactive games that you can play in line ( so both lines have some thing fun to do.) If I were you I would either keep what you have or have it latter in the day as there just are two many walk on rides for the first 60 to 90 minutes of park opening
