This thread is so helpful!, I have been panicking with this whole testing situation (My trip is in September), I was afriad an Uber would not want to take us to a drive-through covid test, but I will try the Cab option as someone mentioned, has anyone done that already ?. Renting a car is not an option for us, so it has to be either Uber or Cab if thinking on the Walgreens option.
Other options I have been looking is to find a place close to WDW that does Testings with an appointment, one option was Adventhealth but I saw many reviews of people saying the waiting time was insane, hours long, even with appointment. So now I am looking at Fasttestnow or Urgentcare247
