I am steering clear of Ambassador for personal reasons.
I just cannot believe operators (CMV) can treat people with such little respect and then start up a new company without any responsibility to previous dealings.
I am sure you can get it sorted, sometimes it is just a glitch.
Recently my wife's card was declined for what was a $7 amount while overseas, my card which is the secondary card on her account, worked.
The Eyre Highway between Balladonia and Caiguna in Western Australia is the longest straight stretch of road in Australia, at a long 146.6 kilometres or 90 miles.
I have used Meriton, Adina, Quest, Oaks, Metro, APX and Sebel apartments over the years, I just pick which one suits my budget and location required best.
These are currently ranging from around $1050 to $ 1700 for the 4 nights in a standard studio or 1 bedroom apartment.
