When I asked this same question last year, I was told that it was indeed faster to go to MK and take the boat to Ft. Wilderness. We did that and had a great time just on the boat ride. We were arriving late in the afternoon and were worried about getting there on time. We allowed for an hour and had plenty of time. It was my 5yo nephew's 1st time at WDW and he was just thrilled with the boat ride. He also enjoyed the show and the food!
