I'm not sure where to post this..

I have priority pass. I'm flying PE from YYZ to MUC on LH 495 on Friday the 19th. I get into ATH

I get into YYZ from BNA on AC at noon and don't leave until 8. I booked two separate flights so I need to go through customs, get my bag and check-in with LH. I'm flying out of T1.

What's the best way to spend that time? I think that I might only have access to Plaza Premium at E77 but I'm not sure.

I don't think it matters but I'm a silver on UA.

I don't drink if that matters!

Thanks!
Justin
