I have three questions.

First, my spouse and her friends are thinking of going to DT KL for a few days in Feb. Can I book one room under my name (HH Gold) but she and her friends check in and I still earn points that count towards status?

Secondly, if there are three people in a room, should i choose 1, 2 or 3 adults when i make the booking...knowing that the "spouse stays free" for HH members. I'm not too worried about breakfasts only available for two.

Lastly, is the 1 king bed deluxe suite big enough for three people (2 on a bed and 1 on a sofa) or should i hope to get upgraded to a 1 king bed executive suite which is much bigger?

Thanks in advance for helping me answer!
