I loved the boat ride over the summer. The resort boat dock is the closest transportation to the MK turnstyles. It was very relaxing, and much more civil than the cattle call walk to the bus stop.... But I'm not sure the boat ride was faster.
FWIW, there are a mix of boats used. The smaller boat is not accessible (if you are dealing with scooters or strollers)
That said, with the construction, I probably wouldn't choose VWL.
