Here are some Tips for Wedding Dash 2:
 
1: Seat the fastest eaters first, and the slowest eaters last.
 
2: At the end of each level, make sure the fast eaters are seated first, and wait for the slower eaters to be seated until they start getting really mad.
 
3: Listen closely to the couple's requests at the begining of each level, every point counts when you get into the hard levels.
 
4: Pay close attention to what the grandpa is eating, he easily forgets what he was going to have next, and its your job to figure it out.
