No particular service issues come to mind regarding my weekend stays. Generally, its been pretty good. Certainly as good as during the week.

Using reward certs, vouchers, BOGOS, etc., is a totally different matter. I would say down through the years there's a problem about 80% of the time. "Scorecard" as follows....

"Mistakes Made in Hotel's favor " 100% of the tiime".
"Mistakes Made in My favor" "0% of the time"

I must point out, however, that the mistakes are almost always quickly and easily resolved. But this is still an annoying and chronic problem that's been written about before. And I'm not overstating things with my "scorecard", at least four out of five times there's a glitch of some sort using any cert....and not once has any "mistake" ever been made in my favor.

BTW, I also always make it a point to make a photocopy of both sides of any Marriott-issued documents I ever surrender to the hotel.
