The reported overall average from plane landing to resort drop-off via DME is 70 minutes.
When I went to POFQ, I got there in 56 minutes. For was the next stop, and I'll bet they got there within 5 minutes after I arrived at POFQ.
Since there are no pre-set DME bus routes and no pre-set groupings of resorts on a bus, there's no way to know for sure how long it "usually" takes to get to any one resort.
