From pictures I've seen in online media [1], it seems they're sleeping on the floor in the foyer, not in suites. Probably works better for surveillance purposes to have them all in one place.
TBH looks fishy to me. Article claims there's 10 princes and 38 officials. But there's hardly 5 beds on that video, which could just as easily be stuffed with cushions. And why are there guns lying on the corner with the guard being on the other side?
Looks like PR work while they stay in their nice rooms.
