I have a long layover in BKK before travelling to DOH at the end of this month, does anyone have any experience of the slumber rooms in the TG F lounge? Are they quiet enough for a few hours' sleep, so no announcements? Is a blanket provided?

I have very little luck having a reasonable sleep in the few sleeping areas that airport lounges have, usually due to noise. That certainly applied in the rooms in the old QR F Premium Lounge at DOH, at least they had blankets for the bed but as a room it was very 2* accommodation. The CX cabanas in HKG F Wing have no blankets, and PA announcements making sleep almost impossible, and they don't encourage you to stay more than an hour and a half anyway.
