Now, this question is obviously for the people that read this forum. At least a little internet savvy.
Why would you use a travel agent or booking site?
From what I've seen the savings are negligible. Why wouldn't you just book direct?
I've used Orbitz and other sites like that as well as Tripadvisor when visiting a city for the first time just to find out what's out there and what's available in terms of flights, hotels, etc. But I never book through them.
(The only exception, for me, is that I have used Priceline a few times when price was the only objective and I didn't really care where I stayed.)
Or am I wrong? Are the savings really that much more than booking direct?
