Online pre-booking is obligatory as they don't accept walk-ins and are invariably full/turning away Priority Pass holders and others with free access by midday. The Plaza Premium Lounge T1 is usually more quiet, but only beer and (debatably drinkable) wine is free. Upsell for spirits (as well as shower use). I've slept in both and find the slumped-in-chair snooze at PP T1 less uncomfortable and never got dirty looks from the lounge dragon. So... less of a zoo, friendlier and nice view of the planes on the apron, but the alcohol is better at SATS T3.
