We just returned from WDW this past Saturday 1/23. We went to the maingate complex test site on Friday 1/22. It opens 8am, there is no appointments, it is walkup, we got there 7:30 am, there is 2 lines, one for families (2+) or single line. We were a family of 5, with 2 small children (6 YO, 3YO). When we got there, there was about 8 families ahead of us. We pre registered in which they send you a barcode they scan. About 7:50 am the National guardsmen came around to make sure you were registered and had the barcode. They opened 8am, we got to the window 8:20ish. They confirmed each member of our party, scanned the codes and gave you the swab for you to self swab, 1 by 1. We did the kids ones for them. This was the rapid test, we had our results by the time we got to Animal Kingdom parking lot which was 12 minutes away. I heard you could request the PCR test if you wanted, but most states accept the rapid so is what it is. It was quick and easy. I also used in back in sept, but then it was drivetrains up, appointment, and PCR test, got results in a day.
