I am wondering whether to purchase travel insurance for my upcoming vacation to Australia. We have a 2 week trip planned (Dec 21-Jan 6), starting with a few days in Sydney, a coastal drive down to Melbourne and ending with a couple of days in Uluru before flying back to Sydney and on to the US. The Voyages travel centre with which we booked our Uluru portion of the trip is "encouraging" me to do so, but perhaps they are just trying to make some more money off me. My husband and I are on a budget so really do not want to spend several hundred dollars for an unnecessary expense. Suggestions?
