I received a "Single-Visit Station Lounge Pass" good for "entry at any ClubAcela, Amtrak Metro Lounge, Or Amtrak First Class Lounge". I've never been in any of those lounges for Amtrak so have nothing to compare it to. I dont travel on Amtrak alot but have an upcoming trip in PHL. Did I hear PHL was recently renovated? Is it worth using there or should I save it for use somewhere else on the NE Corridor?
