I just used the PHX lounge Friday and had been there in January as well. It is a hike from the D gates to the lounge, but we had 2+ hours before our flight. We could have stayed there a little longer Friday, but WN showed a 30 minute delay. Then went back to the original time (as well as FlightAware) showing the same info. Ended up being a 45 min delay, but was too long of a trek to take a chance.
