"Do Not Disturb" means nothing here!!!
As a frequent traveler who spends 140+ nights a year in hotels, there is one thing I absolutely must insist upon if I'm to ever frequent that hotel again or recommend it to others: respect for my privacy. In particular, once I've checked in after a long day's work, DO NOT DISTURB ME, leave me alone, let me rest! The Renaissance Charlotte Suites does not understand that basic concept. An hour and a half after I had checked in and gone to sleep, the front desk phoned my room "as a courtesy" so they could conduct a survey of how my check-in went. There is no excuse whatsoever for disturbing a guest once they have checked in and gone to their room, unless the hotel was burning down. Obviously the management doesn't understand the basic concepts of what constitutes good customer service, one of the more basic principles being to leave people alone if you have no legitimate reason to bother them. If you really feel the need to survey your guests (not something the top-notch hotels generally tend to do, since they already know what they need to do to please their customers), then do it when they check out, or send them an e-mail.
