As for charging my credit card, let me put it this way....I've been on the road since '79 and have yet to encounter a hotel...any brand anywhere...that's forgotten to do this!
Yes, even for award stays (Marriott, twice last year)
I really didn't start having trouble until last year, when I had to start checking out at the desk (instead of in our room) because of issues with improper billing/points not posting correctly and having to fax our documentation in to guest services to deal with it. That got old quickly. Combined with a marked variability in room and service quality, it drove our decision to change brands for this year (at least).
