Please note that there are two Hiltons adjacent to Disney Springs. The Hilton Lake Buena Vista is markedly closer than the Hilton Buena Vista Palace.
Here's a map showing the locations in relation to the Marketplace section of Disney Springs. The pedestrian bridges that
hiroMyhero mentioned are shown, as well.

The Hilton Lake Buena Vista has been a Hilton longer than the sibling down the street. If you haven't visiting in a long time and just remember "Hilton", you're thinking about the Hilton Lake Buena Vista.
