DTD is now DS, or Disney Springs.
There are three Hiltons on property at DS easy walks.
Hilton, Doubletree Suites and the Buena Vista Palace (a new Hilton under major renovation).
Stayed at them all.
Hilton is across the street, easy walk, an okay Hilton, not nice like the newer ones. Needs renovation but for points just fine.
Buena Vista, while across the street you must go to corner and cross, less than 10 minutes. Under major renovation, just stayed, room fine but no other amenities.
Doubletree is the farthest and never took us longer than 15 minutes to walk it. Suites renovated a few years ago, love them.
My choice of the three is Doubletree unless one of the other will give you special point deals.
Check
www.disneyspringshotels.co and Mousesavers.com for info about the hotels.
When looking at Hilton site play with days, we found when using points if we added one more day to our trip, especially Doubletree the number of points needed nightly dropped.
Hilton Bonnet Creek is very nice, right next to property with shuttles but not walking distance.
There are lots of Hiltons within 10 minutes of Disney Springs and the parks by car. They usually require much less points. But if you goal is not to drive or take taxi/uber then the above are your choices.
* If you are driving in know that some have parking fees that your points will not cover.
