I intentionally over night'ed and slept in 2 lounges, great experiences:
1. SIN Kris F lounge on the floor (Private room closes at 1am), was to drunk to sleep on the chair, I checked into my 0900 SIN LAX flight at 11pm the night before.
2. AUH EY F lounge, I checked in at 9pm for my 9am flight AUH JFK, had a decent bed and was also drunk.
Anyone else over night in lounges? I would have overnight'ed in the LH F FCT and CX F HKG lounges had they been open and looking forward to over night in the EK DXB F and maybe QR J or F (if and when it is ready) lounges.
