Q. I'm looking for the best airfare, cruise, and hotel aggregators. Which site should I be using?

A. That’s a hard question to answer because there are so many good ones and they all have different prices at different times.

I recently saw some great airfares on Orbitz to Rome that were ONLY available on Orbitz—not on Expedia or Priceline or anywhere else.  And then I saw super low fares to South Africa on KLM that were only available on Priceline, not even on KLM’s own website, which were hundreds less than any other option.

The same applies to hotels. I booked a room in Boston at the Fairmont Copley Plaza on a site I’d never heard of, saving $200 from every single other hotel booking option. I did call the hotel directly to make sure my reservation had been made and all was in order.

I think TripAdivsor does a very good job offering a range of hotel booking options (that’s where I found the Boston hotel bargain). Plus, you can read the most extensive number of hotel reviews while you book your room.

CruiseCritic.com is a great place to look at cruise aggregators.

For airfare, take a look at BookingBuddy.com but be sure to search all the options offered (there are sometimes 25 different aggregators and they may not all have the same price depending on the airline, dates, etc)

So the answer is that there is no perfect aggregator for every trip and every travel date. But it’s often worth looking at all the options presented because you can save hundreds of dollars.
