Was in the IST lounge this past Sat/Sun for the first time.
Arrived around 11pm Sunday for a 2am flight to Male.
My observations in no particular order:
Very busy upon entry only to get busier.
Wifi is cumbersome to get access to with the kiosks and very slow. Ended up using my data instead.
Food selection at various stations was excellent and plentiful until around 00:30 Sunday, then started to disappear.
Wine unavailable past around 00:30 as well, but hard stuff was still there.
Pool, golf, race track, TV pit all great entertainment if so inclined.
Is it a nice lounge compared to most others that I have seen? Yes.
Would I show up early just to experience the lounge? No.
