Ball park estimate.....12-12:30 for the pick up....arrival at the port around 1:30P.
I'm sure someone who's been picked up from the Poly will post with more exact figures. I was picked up from POFQ at 12, at 12:15 we hit CBR (I think it was) and were on the road at 12:30. Arriving at the port at 1:30 was actually nice, they early crowd was gone, I checked in and was on the ship withing 10 minutes, had my luggage dumped in my stateroom and hit the buffet about 1:50 (no schlepping cary-on luggage around).
The hardest part is that wait between check out and pick up....that's when you start thinking about all the people who took town cars over and were ALREADY at the ship!
