What is your opinion of the OHG hotel ratings? From your experience, are they accurate? That is, knowing the OHG rating of a hotel and having stayed at the hotel, would you say the rating was accurate?

Reason is, I'm seeing some hotels rated at surprising low and high. For example, the Sheraton Maui is rated as Superior-first class, but I've heard that it is a very, very nice hotel. Also, the Maui Marriott is rated as a deluxe hotel. Does this make sense? Are the ratings for these hotels accurate?
