Or if everyone and their grandmother didn't feel behooved to lug a giant bag through the parks...
I get merch bags, you buy stuff, you have a bag, and the front of park or hotel delivery options are "blah."
The giant backpacks? Why? WHY?!?!? And before anyone come sin and says "well we go all day and yadda yadda.."
No, most guests are in the parks like 3-6 hours. There's no reason to need a giant bag, nevermind multiple people in your party carrying a giant bag.
