There is no T3 arrivals lounge for priority pass. So unless you have access via another means, T3 is a no-go. If your arrival is T4, then just go there since it's a hassle to have to travel to T2 just to use the arrivals lounge.
Indeed I do have access via another means (Asian credit card with a bespoke agreement with PP). Did a little further homework and I think I'll probably give the T3 lounge a miss then. Thanks!
