Ambassador is ABSOLUTELY NOT worth the time or money beyond Titanium: with the bespoke service annihilated, glaring inconsistencies in service levels and lack of guest-accessible perks, I recommend that one should divert all their effort towards attaining secondary status with another chain like Hyatt or Hilton. As countless others above have said, don't expect much and keep your expectations [very] low.

Marriott must know at this point what many think of their highest tier, and I continue to find it utterly bewildering how unperturbed and detached they are from it... but it does tie in nicely with their corporate culture of "owners first."
