I returned Sunday from 9 days at Signature, during which time I charged everything to my room. During past trips, I recall receiving tier credits immediately upon check-in for the room costs. This time, it's been 3 days, and I haven't received any credits for several thousand dollars worth of charges (need these tier credits to hit platinum . . .). Is this delay normal, or is a follow up with MLIFE warranted? Thanks in advance.
