Whether Hilton's reservation for others counts as your points depends on whose identity you use. If you use your ID card to help you book a hotel, then the points should belong to you, because Hilton Hotel points are based on the guest's last name or the credit card used when booking. Before confirming the attribution of points, you need to verify the specific information used when booking. If you use their own ID card to help you book a hotel, the points will belong to them. You can try to contact the customer service of Hilton Hotel, explain the situation to them and ask if you can transfer the points to your account.
