I am HHonors Diamond and will be traveling to Singapore the end of this month with all my inlaws, 15 people total. We will be staying at the Conrad there. I was wondering as a Diamond if I reserve 8 rooms in my name and HHonors account, will all the rooms I reserved be granted access to the lounge? Or must I reserve all the rooms on the Executive floor for them to be granted access? Also how will the points work, will I get points for all expenses that were charged to all the rooms, or just my room?
