Hello! I thought I would share my experience with BeeperMD here! I was in WDW from Nov 1-5 last week, so we had our test booked for 4:50-6:50pm on Nov 2 (exactly 72 hours before our flight, in case there was any delay in getting the results back). This was a last minute trip, so I booked this appointment around 2 weeks ahead of time, and that was no issue. At around 1pm the day of the test I saw that they had changed my appointment time to 3pm, which was too early for us due to our flight time on the 5th. Over some back and fourth emailing with them saying 4pm was the latest they could administer our test, I had to have it rescheduled to the next morning at 9am. Although this was all very stressful, 9am the next morning would still give us enough time to get our results. The next morning came and our nurse was right on time. She called me to let us know that she was there, and asked us to meet her in the lobby. She took us aside to a quiet area of our lobby (All Star Music) and took our test. Was super easy and only took a few minutes. She was very nice, too. We then received our test results the next day, around 28 hours after she took the test. Although the rescheduling of the appointment was very stressful at the time, everything still worked out and I would highly recommend using BeeperMD for your trip!
