There’s a thread with the numbers, let me see if I can find it…
Here it is:
A little over 11 minutes of travel time, plus you have to de-board and re-board at CBR on the way. I’d guess 15 minutes travel time if there is not really a line at CBR (or Epcot). Ideally, this will be faster than walking or riding the boat, as long as you can walk out the IG, hop right on the Skyliner, and transfer with no delays at CBR. I’m looking forward to it, with the exception of it bringing crowds to the IG.
