Expedia is one of the most used travel sites, though there are many consumer complaints about them, too. The top five travel sites in the 2011 consumerresearch.com reviews were Kayak.com, Yapta.com, Hotels.com, Priceline.com, and TripAdvisor.com. Google survey says that Orbitz is the number one site. It is best to do your own research to make the choice that considers what is important to your travel needs versus what particular agency/site offers.

Undercover Tourist is a reliable website for booking travel. The prices are comparable to other websites that offer travel discounts. I especially like their options to book attractions tickets.

The overall consensus based on comments of those that have used itravel2000 is too ambiguous to gauge whether or not it's a completely reliable site. The website exists, and is a travel site, but there seem to be as many customers that had a bad experience with them as there are customers that had a good experience with them.
