No way to know for sure. Here's why....
it takes about 10-15 mins to get from the gate to the DME area. Then, you are sent to your resort bus line. Okay....you could walk right through that queue and onto the bus. Or, you could join others in the line and wait for 20+ mins. Most likely, it will be around a 10 min wait to get on the bus. Then, you could get on the bus, sit down and leave straight away...or, you could sit and wait for 20 or so mins! Then...you get on the road....your resort could be stop number 1 or stop number 4.....that's a difference of 15+ mins.
The average time, from gate (note I say gate, not touchdown.....flight arrival is wheels down, not at the gate..that could be a difference of 15 mins right there!!) to your resort is about 70 mins. It could be 60 mins, or it could be 90. Figure on 90 and you'll be thrilled when it takes 70!
