We really liked the Hilton! It is a short walk to DTD, the rooms and grounds are beautiful and very clean.
The busses were fine. There was very little waiting, no more than we have experienced for on site resorts. The bus stops at some of the other hotels in the DtD area, but most Disney busses stop at more than one resort, or at least at a few bus stops.
If I could change 2 small things, if would have been nice to have a balcony and a slide at the pool. Not complaining. These additions would have made it perfect.
