Over the course of my trip, I've stayed in about 15 different hotels, including eight different hotel chains -- everything from Rodeway Inn (three times) to the W (New Orleans) to Spring Hill Suites (Louisville). My conclusion: the hotel star rating system is a sham.

My 2-star Econo Lodge in Pigeon Forge, TN was ten times nicer than my 2.5-star La Quinta Inn in Lubbock, TX, all of which wasn't THAT much worse than my 3.5-star Crowne Plaza in downtown Denver.
I booked tonight's stay in Omaha through Orbitz at a 2-star Holiday Inn Express, chosen mostly because it has laundry facilities. Laundry got done, but really, the hotel's best feature seems to be my room with a view.

Yes, that is just as it seems: doors next to the tub open directly into the bedroom so that you can watch TV while taking a bubble bath. Or
talk to your loved one in bed while you sit on the crapper. Claaassy.
So, what's with the hotel star system? Apparently the star ratings are as
squirrely as those of credit ratings agencies. As a
lil' internet research revealed, a hotel's rating is simply determined by the organization that's rating it, be it Expedia, Frommer's, or AAA. Those ratings may not be updated regularly, nor is the scale consistent from one website from the next (4-star max vs. 5-star max), and most importantly, the criteria for reaching certain star levels vary. For people like me, who regularly book travel using multiple sites, this is just cruel.
As I see it, there are two solutions. 1) Use a travel website you trust, and use it consistently. Or, better yet, stick with Tripadvisor, the savior of the XXX-Country Tour. TripAdvisor aggregates user ratings and then gives me a certain number of thumbs up based on those ratings. Thus, I'm not dependent on one organization's star system, but the collective's.

Tonight I stay at the Majestic Hotel in Chicago. Hotels.com: 2.5 stars / Expedia: 3 stars / TripAdvisor: 4 thumbs up. I'm banking on the latter.
