Absolutely.
Being pleasant and reasonable, I agree, nets out to better results than being obnoxious and demanding. (And that goes no matter who is signing the front desk clerk's paycheck.)
But the latter harkens back to the point of and reason I introduced this thread - the seeming inconsistency of interpretation of the MR Platinum/Gold Upgrade T's & C's/Practices/Policies between personnel on Marriott's payroll (by dint of the property being owned or just managed by Marriott International) and those working for a non-Marriott hotel management in a Marriott-flagged brand (particularly Marriott full-service, Renaissance and JW properties).
I posted a direct question regarding it on the companion thread (referenced in post #1, above) but have (not surprisingly) not received a response on what is probably a hot-button issue which engenders complaints to Elite guest service lines.
I hope that anyone from Marriott reading my posts on this subjects understands that they have not been created to be hostile or disagreeable, but rather to reflect the opinion and experience of a Plat with a very long history (overwelmingly pleasant), with Marriott.
