Hello, I am sure this has been asked before but here goes. I am considering going to Disney in June with my parents and my son. Problem is my son and I can arrive early in the morning and enjoy a day at the parks and my parents who live on the other side of the U.S. won't be in till the night. Can we all use DME even though we are in two groups? Is there a special process since most likely I will have the coupons and they won't? Can they just go to the counter? Thanks
