It's now called the Regal Sun Resort (formerly the Grosvenor's). I stayed there when it was the Grosvenor in a tower room and I enjoyed it very much. The hotel had been showing some signs of wear but I think they've spruced it up nicely since the renovations. They were very close to DTD and their bus service was good..although the bus stops at the parks could be far.
Beware that this hotel charges a resort fee and precharges your card for incidentals......if you're using a debit card it'll take a chunk out of your spending cash.
