I have taken DME to POP many times. Usually, it was the first stop...but there was the one time it was the last stop!!! That ride took me about 90 mins, from gate to resort. Most other times, it was closer to 70 mins.
Earlier this month, I took DME to AoA. We went to AoA first, then the bus continued on to Pop, and then finally to CBR.
If you land, ontime, at 5:30, you can plan on being at Pop no later than 7ish. And most likely, sooner than that. But, I always plan on the lengthy side.
