People often ask me about my go-to sites for booking travel. Ask and you shall receive---perhaps more than you bargained for. Here are my not-so-secret, preferred travel sites divided into categories so you can refer back to this page when you're planning your next jaunt abroad.
There are thousands of travel sites that do a thousand things, but, the below candidates are the clear and simple 'winners' as far as offering a great user experience and good prices. Let me know if there's a site or category you'd add.
Flights In addition to always checking the sites listed above for flights, for routes I know well, I book through an airline directly, otherwise: DoHop SkyScanner HipMunk Allegiant - For short-haul trips out of Vancouver or Seattle. See my best practices for booking with Allegiant here. Seatguru.com - Find out the best seat on the plane, before you fly!
Cars I'm not too picky about what car I drive, so I usually book my rental vehicles via discount travel sites (below) or the rental agency direct.
Cruise Vacations To Go - A great place to find excellent cruises from most major and boutique lines in one place. Check out what's available in the short-term with their 90-Day Ticker. CruisesOnly - USA's largest cruise agency. RepositioningCruise.com - A great place to find cruises with interesting and off-beat itineraries in the off-season.
Note You may be wondering why I'm not featuring Expedia or Travelocity in the above list. Though I've booked multiple hotel room stays with both of these travel suppliers, I usually---but not always---find better prices elsewhere. If you do plan on booking through one of these sites, compare and contrast the hotel you're looking at on both sites, as well as on the Canadian and US versions. Sometimes the price difference is minor, and sometimes it is major.
