That is crazy. They need to eat a slice of humble pie and ask advice from corporations who are known for getting the job of People Moving done efficiently. Look at how Disney knows how to move people. Sure they have their moments when it's less than stellar but overall given the scope of size of WDW, they're pretty amazing. (Land, boat, monorail, skyliner) They use a variety of methods to get it done. Some resorts have more than one method.
Look at Chick-Fil-A. Their drive throughs are sometimes 2-4 lanes wide, and full. So they put people out on foot with ipads to take orders and pay in advance instead of making everyone wait to get to the squawker on the loudspeaker to order, then pay at the window. I've been in line with 30 cars and we're still through it with hot food in 15 mins.
