Hi all,

Haven't been through SIN since the pandemic. I will have a long layover (12 hrs) later this month, and will be flying late night on an NH flight in Y from Terminal 1.
Are the SKL lounges in T2 & T3 accessible to *A Gold (UA 1K)? Are there any lounges in T1 instead for *A Gold that also have showers?
I also wanted to get out and visit Singapore for a couple of hours, as it has been almost 4 years I haven't gone there. Anything I should know post-COVID? I will drop my carryon bag at the baggage storage facility, and plan to come back a good 4 hr before departure.
Thanks
