I have a large group of friends going to Bali for 10 nights and I will be joining them for the first part of the trip.

We will be sharing rooms to help reduce costs. Unfortunately there is one person who is an odd one out so has to pay for a single room.

If I book a twin room in my name for 10 nights, and then leave back to work after 5, can the single person move into my bed even though the room is technically booked under my name?

Also, would I get the points for the full stay even if I am not there for the last 5 nights?

Thanks!
