Lowcost alternative from somebody who has n lounge status: What about T5 B or C? Those terminals are relatively quiet, ample seating space (just go to an unused gate). If ou want a table: at the Wetherspoons in 5B, there are tables with a view of the appron as well as normal tables. The Starbucks (or is it caffe Nerro) in 5C is good as well but a but dark.
