Hoping to get any recent DPs on this.

we’ll be arriving on a TR redeye into T1, with a connection to SQ about 13 hours later (same calendar day). Don’t worry, we’re not staying airside the whole time…will be meeting some friends in the city late morning, but looking to get a bit of a rest/refresh before we do that. Looking to T3, since we’ll probably head over there right after arrival anyway, since we’ve got a couple of our carry ons we’d like to leave at luggage storage and pick up before our flight back.

Can anyone confirm if SATS lounge in T3 accepts arrival pax based on arrival that morning - (I’m pretty sure I’ve done it for ambassador T2, or maybe Maharaba?). Or really, if any of the other airside PP options will work? Or if departure BPs for that long prior will be accepted. Also, if we come back to either same or different T3 lounge prior to departure, would we be allowed to enter again based on the same PP membership?
