When we stay at BWV, which is a lot, we usually take the boat. It would most likely be an addtl 7-8 minutes to S/D. It is a nice easy walk. But, if it's hot/humid/you're tired, then taking the boat is nice also. We would rather be walking than standing in a line, waiting for the boat. So, if there wasn't a very long line and the boat was there, or in sight, we might ride. But, late at night, after park closing...forget it. The lines are huge. By walking you can reach your resort at about the same time if you leave 1/2 minute before the boat does.
Yep, we have usually walked back and forth...and I'm waaay old...mid-fifties.
