The new Trump hotel in the Old Post Office Pavilion will have a lane on Pennsylvania Ave for its valet parking. As far as I know, this is the only hotel or restaurant on Pennsylvania Ave that has control of a traffic lane in front of its building. Mayor Bowser and the DC Council insist that the area will be accessible to pedestrians and protestors during special events. However, because of the lane restriction the Japanese-American Society of Washington had to relocate its street festival during the Cherry Blossom Parade from Pennsylvania Ave to Navy Yard. This was the first time in 16 years that they didn't have their street festival on Pennsylvania Ave.

Trump’s team also promised the GSA when bidding for the contract to use a particular architect for the project. But Arthur Cotton Moore, an architect who had renovated historic buildings in the area, was not retained once the deal was signed. It should be noted a $32 million tax subsidy the Trump Organization has applied for hinges on preserving the building’s historic character. I wouldn't be surprised if they get the subsidy regardless of how the building is renovated.
Trump had also agreed to bring on a multibillion-dollar real estate investment, Colony Capital. Instead of teaming up with Colony as advertised, Trump put the federal lease on the property up as collateral to secure a $170M loan.
