I've been looking at hotels on Hotels.com, Expedia, Priceline, Travelocity, and Bookit for a few days stay in October. Just one hotel room for two people. Since there's only two of us, we are not interested in a condo, villa, or anything more than a hotel room, but I'm getting really confused with all these sites. Which one do you like the best and why? Do you think there's a lot of difference between a 3 star and a 3.5 star hotel?
