 In an effort to reinforce the success of the hotel, Leppert led the City Council to lobby Dallas Area Rapid Transit (DART) to change the alignment of a proposed light rail line through downtown; under Leppert's plan, the line would be diverted from the center of downtown to stop at the hotel and would include a subway segment that would travel beneath the convention center to an underground station at City Hall before rejoining the original alignment.DART staff, however, reported that, at $824 million, the proposed realignment would be more expensive than all other options being considered, exceeding the cost of the cheapest alignment by $315 million.They also pointed out that the Federal Transit Administration makes the final call on where the route should go, and the hotel alignment had been shown to attract fewer riders, at higher costs, than other options.
