Alrighty, then how about Priority Pass or AMEX Plat card holders? Or even something with paid access? Haven't finished booking our last leg of the trip for location, but thinking Santorini since we can fly direct to ATH from there. Looking at the flights into ATH, most land mid-morning and our flight out is at 2pm.

If not, any recommended places to hang out at ATH for 4-5 hours that are somewhat comfortable? Comfortable to us is this when we sat at the upstairs cafe in the Rome train station waiting for our train and playing cards and drinking lots of expresso for about about 4 hours and had a blast - so we aren't super picky, though we are now getting lounge spoiled over the past 2 years.
