I did a lounge recon on night Jun 17 in SIN arr at 21:00 - dep 00:30 - inspected all SIS lounges in T2 and T3 - here are my observations:
TPE - Yes lets start here - quiet on arr - quiet whole time - lounge quality perfect as norm - serving VCLGD - gotta love that.
T3 SKL F- few pax - tons of eats - usual great F & B offerings - didn't check Champers on offer
T3 SKL J - only half full - tons of seats - showers not fully occupied - great selection of F & B as usual - Bolly on offer
T3 SIA Gold Lounge - plenty seats available - I would say half full - good food selection but drink selection here appeared quite limited.
T2 SKL F - virtually empty - identical offerings as T3 but no pax.
T2 SKL J - virtually empty - identical offerings as T3 but no pax.
T2 SIA Gold Lounge - virtually empty - identical offerings as T3 but no pax - in fact better drinks offerings here - but ALL 3 lounges in T2
EMPTY.
Now good people I know SIAGL is not up to SKL - no showers or toilets in lounge is a real bummer - but from what I saw the other night plenty space and food offerings good - drinks in T3 a bit bare but T2 fine - was that timing? Who knows.
Now in T2 when you go up escalator from chocolate shop to lunges - over on your far right is SATS Premier Lounge:
Before lounge upgrades in T2 this was the SIA Gold Lounge and indeed it has showers in it - but new SIAGL does not - clearly this was significant mistake by SIA. If it helps if you flying Scoot you can get a shower in Premier Lounge.
I was chatting to girls at desk SIAGL in T3 for like 10 mins discussing all things lounge - they were fully aware of pax being so disappointed no shower - whilst I was chatting I saw continual stream of SQ pax trying to get in here with SQ J BPs - unbelievable. Clearly they came from B gates up escalator new Ambass Lounge then wandered along mezzanine.
Hope this helps
