Why does this bother you? Because you think everyone using an ECV is fat and lazy? Far from it. If I remember correctly, the boats from POR, POFQ, SSR and OKW have a step down. I sure hope the boats have ramps, like the buses, to facilitate those who are using an ECV to safely board the boat.
Another bad management decision by Disney. Yes, I'm sure there are visitors taking buses from parks to SSR to get to DS or vice versa. So what. If Disney REALLY wanted to fix the problem of people parking, for free, at DS to get to the parks, then make them pay for parking - if you're an AP, include free parking at DS in the benefits. I'm so f***** tired of, as a resort guest, funding a transportation system for non-resort guests. You know what, make the buses for resort guests only. Tap you MB and if you're not staying on property, you don't get to ride, unless you pay to get on, 50 cents a person. Disney touts the buses as one of the reasons to stay in a Disney hotel...along with EHM (and we've seen how they tried to shake down guests for that). The buses for resort guests only, just like EMH.
Universal has buses/boats from their resorts. But only resort guests can use them. Why? Because there's no free parking...not at a resort ($20/day), not at the parking garage, so there's no advantage or incentive.
Somehow I don't think this is going to last. Either someone staying at SSR will sue under ADA or the reservations at SSR will decline significantly. And DVC members will think about selling their interests. Has Disney forgotten how damn hot it is from end of June to early October. "Hey, just let them walk... they'll still come.". Yeah, right.
