I went Aug 2021. It was very difficult without having your phone, especially an IPhone. All the apps drained my battery quickly (Samsung/Android). WDW gives top priority to Iphones and does not sell chargers/power banks for any other device. I rented a power bank at my resort (Contemporary), after being led on a wild goose chase on the monorail loop as to where I may be able to purchase one. Answer: nowhere. The rented one ($30) never made it over 10%.
All menus are now scanned to your phone. At QS, you can read a board and at TS you can ask for a paper menu, but expect an eye roll and long wait for one.
QS at the Contemporary last year was mobile only. Not sure if that was due to construction in the tower.
QS at Epcot, specifically Mexico, waas very very confusing when not ordering via the app. No real line to order at the counter and no way to call you when your order is ready. You need to keep asking.
I hated the whole thing! It made some pretty frustrating moments during my vacation, especially when all I wanted was a drink! Can't a girl get some water please?? !!!!!!
