There should appear the readings of the tracking device on the screen, which informs you of the current distance from the target. You do not need to roam for to long, especially that the destination is not too far away from the bridge. You need to get to the Diamond District, to the Gotham City Royal hotel located in the Eastern part of the district. I recommend that you approach the hotel from the South-western side, thanks to which you will bypass the snipers, among others, who are guarding the nearby communications tower (unless you have eliminated them already).
Note! If the readings of the tracking device do not show on the screen, make sure that you have not marked another location for your current destination, e.g. connected with some side- mission.
Do not even try coming near the hotelís entrance, because it is heavily guarded by a SWAT team armed to their teeth. What is even more, this area is constantly being monitored by an elite sniper. Instead, go to the South of the main entrance and find the path shown in the screenshot, where there a few police vans parked. The road leads up to the West, towards the buildingís side entrance.
