My mother (now 70) has made the trip with DD and I for past 4 years and going again with us in Sept (YC). She has had problems in past with various things. Last year she really needed to cut the walking. We stressed on the reservation and room request fax that due to her "age and mobility issues, we really needed a room convient to main elevators". Room assigners did a very good job. In fact, at boardwalk, the desk clerk told us at check in that assigner had assigned room and noted DO NOT MOVE in their computer.
Will be doing the same this year as now her legs are the problem. She came back last year with so many aches and actual sprained hamstrings. But she won't give up going!
She actually picked going back to an EPCOT resort because it seemed that boats and the closeness of the bustops was better for her. And she can go to WS on her own while DD and I go to another park.
The standard rooms will face the front of the resort-not the water and close to elevators will put you by the front drive/entrance. Because of that, you might want to ask to be away from the bus stop as well.
Have a great time!
