No. But the boat is very relaxing, rums about every 15 minutes, and about every other one is one you can roll a stroller or ECV on. The bus is also very quick, and usually does not share with other resorts (occasionally it shares with Fort Wilderness).
You can take a boat directly to MK from WL or you can take a boat from WL to the Contemporary and then walk to MK (about a 10-15 minute walk). We did that a few times because the boat to the Contemporary arrived first.
