We used it a few weeks ago and our pick up time was 3 hrs 15 minutes in advance because we had to stop at another resort to pick up more guests. It took slightly longer since there is no RAC, and the driver had to load everyone's luggage under the bus. But the lost time there was made up by the very short lines at the airport.
I would also add that while social distancing was great on DME upon arrival, departure was a different story. The driver made no mention of asking guests to space themselves and there was no assigned seating on the way back like there was on the way to the resort. The bus was only half full so there was ample room to spread out, but people still mostly congregated in the front of the bus.
