It has nothing to do with how savvy anyone is with technology. I am extremely savvy. What I hate doing is scheduling everything I have to do on vacation to the very minute...including bowel movements. It is ridiculous at what is required. You have to plan dining 180 days out, then you have to schedule FPs. Then the FP times make you go revisit dining reservation times, then back to FPs, then the FP times are gone. Then, you go on The People Mover with 90 minutes to spare before ADRs at Ohana's. PM breaks down, you are stuck for 45 minutes, then it starts back up and stops again. You are calling on your phone to Ohana to tell them you are stuck on a ride. You miss your FP for 7DMT because you have to run to Ohana. You have to decide to take the monorail or boat. You go monorail, monorail stops for 15 minutes. You run like chickens with your head cut off to Ohana 15 minutes late and now have to wait for an available table. Now you are waiting with everyone that had reservations at 6PM - 6:30PM while yours was at 5:45PM. Tables are limited because they have already been seating. As you wait, more people come in at their ADR time. You finally get seated at 6:30PM. Drinks and apps come out slower because it is now packed. You are looking at your time because Wishes is at 8PM. It is pushing 7:45PM at dinner. You have to decide whether to watch it. Now you are rushing to get the bill. Everyone else is too. It takes 10 minutes to get it back. Now you are trying to run out to the Poly beach and it is about half over now. Your FP for Space Mountain was scheduled for 7:45-8:45PM. Now wishes is over and it is about 8:30 trying to get to the monorail. You are now late and miss out on those FPs as well.
