I've also booked on Australia Nov 25...you only live once afterall. 

Great news.

Just had a Hep B jab today and can't wait to get going.

I'm booked for this 4th March '25 departure to Chile,Argentina &Brasil. Was wondering if anyone has any helpful information about what currency to take with me. On one site it recommended taking US $ rather than the local currency. Visiting 3 countries makes this hard to calculate how much cash to take. Naturally this is for the smaller purchases and to pay at those  out of the way places we will no doubt visit
