Where in the world?

I guess I'd better tell anyone who doesn't know where I'm going what the plan is. It is a fairly detailed plan but there is some scope for flexibility.

The trip is broken into three legs, the SE Asia leg, the Oceania leg, and the South American leg. The plane ticket sort of puts limits on how long each of these sections will be.

SE Asia
Jan 26th Fly into Bangkok.
Will be in Thailand, Cambodia, Malaysia and Singapore for 5 weeks. Angkor Wat (Siem Reap) is the must see destination in this section. There probably not actually that much trekking in this section as it will pretty much be city to city, with Bangkok, Phnom Penh, Kuala Lumpur and Singapore getting 4 or 5 days each as well.

Oceania
March 1st Fly into Sydney.
I'm about a week in Sydney (no other parts of OZ) and then onto Christchurch for 3 weeks in NZ. Probably about 2 weeks in South Island before a week on the North.

South America
April 1st Fly into Santiago.
This is where its a bit less defined, depends on how much trekking I want to do by then. Obviously the Inca Trail and Machu Picchu in Peru are the ultimate goals, but before that there will undoubtedly be other treks in Chile and Bolivia (maybe Argentina if Bolivia gets a bit troublesome). I'll be about 2 months between the three countries. There is then a final week in Rio.

In total the trip is about 4 and a half months. I'll be home in early June. There is a lot in it and it remains to be seen whether I'll be able to cope with the hectic schedule I've set myself. I'm more worried about coping for 4 months without having a computer in front of me for 50% of the time, but at least I'll have this blog and some internet cafes to ease the pain.
