E-Ticket - is the $$ savings worth the will call line?

I am considering buying E-tickets online for our family trip to WDW in March. Since it will be busy, I am wondering if the will call line will add a significant amount of time for our morning rush to the rope drop? Also, will we need to wait in the will call line at each park? Is one park busier than the other for will call pick up - i.e. should I arrange our touring plans for the first day for a park with less of a wait? So many questions…!!!

Do you have magic bands? If you do the tickets automatically link.

Nope, this is our very first visit and we’ll be staying offsite. However, I did find an option for free shipping! At first I thought the deal was only for an E-ticket purchase. We have time to wait for snail mail, so it looks like we are good to go. Thank you for the response!
