Paying for the room in resort?

Q: My friend will be flying from Europe to Aruba and he will be staying with parents at the hotel. But I want him to stay with me when I come to Aruba. I already pay for my room at the resort(price per person). If he comes and will be staying with me in my room, do I need to per for him too? Extra for the room?

A: You need to sneak him into the room, and don't move his stuff over from his parent's room cause when the cleaners will come during the day they'll spot it.
