Next year, a coworker is heading off on a RTW trip - an extended honeymoon - sound familiar?
Particularly if you're in/from New Zealand, this kind of travel makes sense.
It's economical
A RTW ticket with multiple stops can cost the same as a single return ticket to, well, almost anywhere in the world. STA's cheapest RTW tickets start at just under $2000 - that's the same as a typical return flight to London.
Our currency is strong right now
So you get more bang for your buck. Our money basically gets halved in the UK and Europe, but it's been a lot worse in the past...
It's efficient
You can squeeze more out of your time away - experiencing more, staying longer.
And tying back to my first point, on a per day basis it's cheaper. Your costs are lower when you travel slower, staying put in places rather than moving around like a speed demon cramming everything into a few weeks or a few days.
Plus, play your cards right and you can seriously cut down on jetlag. Another colleague reckons she loses a couple of days at either end of the trip every time she goes back home to the UK. On our RTW trip, though, we had zero jetlag. We worked our way around the world and it worked out perfectly in regard to time zones and flights.
