Infiltrate the Royal Hotel

After taking over two rackets in this district, this story mission will become available. Talk to Donovan to get some intel on taking down Tony Derazio. After the cutscene, you’ll have two options: go loud by walking in through the lobby and using the elevator code or steal Dominick’s car and enter quietly from the garage. Two objective markers will appear in the map in relation to these tasks. We’ll take the covert option for this walkthrough.

Head to Dominick’s location and clear all of them, including Dominick. After taking them out, steal the car and drive it to the Royal Hotel. The gate will open and you’ll be allowed inside. Park anywhere if you like then head to the small monitoring room. Kill the lone guard there then take out the others if you want as well.

Use the elevator to trigger a cutscene. After that, you’ll be in a hostile area. You can sneak around the enemies and head for the exit or you can easily stealth kill them all one by one. After reaching the exit, you have to go to the upper floor to find more enemies. You can actually go loud at this point if you want; just use your intel view frequently to prevent getting flanked by the enemies.
