At one time, Marriott rooms used to have a guest survey to fill in (paper form). If I am unhappy or for that matter very happy with an experience during a stay, can I request a Guest Satisfaction Survey and if so how ?
I believe it is the policy of Marriott to stock all front desks with a reasonable inventory of "Guest Survey" cards for guests to complete. These cards are usually "property-only" surveys and do not influence the Marriott corporate rating. Only the e-mailed survey requests directly affect the property's corporate status for customer satisfaction. IMO, the most "powerful" (in terms of influence) is an e-mail sent to firstname.lastname@example.org with comments both good and bad.
