It also depends on what room you end up with at BWV. If you are at the very end, near their tennis courts, I believe it is a shorter walk from the end stairwell and then along the path to DHS. Otherwise, from that area, you need to walk all the way to the boat dock and then endure a 30 minute ride to DHS. It would also be a longer walk across the bridge to the Swan/Dolphin dock.....and also be aware, that in the earlier mornings, the boat to DHS can be quite full by the time it gets to the swan/dolphin dock and I've seen many unhappy guests having to wait for the next boat. With elders in tow, however, I would most definitely at least take the boat back. But again, depending on where your room is, the walk back from the dock can be very long....but extremely enjoyable since there are so many wonderful things to see along the BoardWalk. Sitting on the veranda outside the lobby, looking across the lake is a good resting spot....and if you time it right at night, you can actually see MK fireworks in the distance from that spot.
