Your biggest time suck is going to be the waiting for an elevator, if you can get one immediately, I would say it should take no more than 2-3 minutes to get to the 4th floor (monorail platform floor) and 5 minutes to get to the walkway/bus stop area.
4739 is on the highest floor before club level, and it never took me longer than a few minutes to be where I needed to be. While 4739 is basically in the middle of the resort, the farther rooms aren’t that far away (maybe 100 yards, if that?). So covering that distance might add on an extra minute or two depending on how fast you move. So long as the elevator wasn’t taking forever, mind you
Don’t forget to use the TP room finder section to get an idea of the views from the room!
