The 2 places from the screenshots can be reached from the house. Its a vacation poster in the kitchen. Costs 50$ for a day in the vacation retreat, per person (You can invite the girl from the pool with you).
You can invite the drug girl over to your house from 5pm each day, from the moment you met her. Buying from her won't improve the likability, only gifting her things will (Just like with the other girls).
As for the cop, you can invite her over after she has at least 0 likability. And then same process as the others.
