Pros
Convenient location for public transportation, employee loyalty seems like a better run group than customer loyalty, decent job (as concierge) if you are in college or want an into to travel and hospitality, offices located in US and abroad.
Cons
Compensation & Benefits (lacking for most, but obviously not for all,) negative culture, out-of-touch leadership priorities and management, poorly trained and ill-placed managers (especially ones who work with the concierges--please get them training and better support), technology is still lagging behind but better than it used to be, little to no advancement or professional development
