Back to the subject of priceline and hotwire, I think they are well worth a try. If you are really specific about what you need -- you want to be within two blocks of a station, for example, or you really like Hyatts but you hate Sheratons -- if you are extremely particular, in other words, they might not be the way to go. If you're OK with anywhere in a certain part of a city, and what you want is a really nice room in a well-above-average hotel, then I would not hesitate to use one of them.
I have stayed in some of -- literally -- the best rooms of my life for around $50 a night. And I've done a fair amount of traveling in my life. Honestly. More details if you request them.
Absolutely!! I almost never buy via the travel sites. Like you, I use them to do the research, and then book directly with the hotel or airline. The ONLY time I book via the sites is when the online price is lower.
Also, I use kayak.com because it returns results from multiple sites.
Priceline.com and hotwire.com really do not compare to the usual travel sites -- like expedia.com or kayak.com, for example -- at all.
If you guys don't want to believe me, then part of me is fine with that, actually. I do want to be of service, if possible. But when I started using priceline, my first reaction was, Oh my god, I'd better not tell anybody about this, because there's no way they (priceline) can keep doing this once a lot of people find out about it.
