Planning a winter getaway? If you're booking yourself be warned -- hotel ratings can vary significantly depending on which travel site or guide book you use. Chris Olsen shows you how to know what you're really checking in to.

A getaway to Miami in the winter sounds great. Could the famous Fontainebleau Hotel be a perfect place to stay? How do you know what you're really checking in to?

Travelocity gives the Fontainebleau five stars. But Forbes gives it a mere three. And if you check Frommer's, it only gives the Fontainebleau one star out of three. So who is right? Consumer Reports' Tod Marks says it's important to know how hotel stars are assigned.

"Travelocity sometimes conducts on-site inspections, but that's not always the case. Now, Expedia, when they do an inspection, they alert the hotel to let them know they're coming. And Fodor's actually allows its freelance reviewers to accept free rooms and discounts, with the caveat that they have to inform the hotel that it won't affect their ranking." Marks said.

The Michelin guide, in contrast, does all its hotel visits anonymously and pays for the reviewer's rooms.

So Consumer Reports advises, before you book a room, check a hotel's website to see what the rooms look like, the services being offered and hotel policies.

"You should also take advantage of user-review sites. And best are those aggregator sites that actually lump together reviews from a whole group of different travel sources," he said.

Mytravelguide.com is a good aggregator site, and Tripadvisor.com is good too.

"Look for the most recent user comments because they're apt to have the most up-to-date information about a property. Maybe there [are] renovations or construction going on," he said.

And look for reviews by travellers like you. Business travellers, couples and families will all have different expectations of a great hotel stay.

Consumer Reports says that when it comes to user reviews, it's best to ignore extreme comments, both good and bad. They may have been posted by people with a vested interest,

The AAA ratings are also good. Hotels are anonymously inspected and have to continue to add amenities in order to maintain their rating.
