If I was locked in a zone for a week, I think I would chose The Steppes of Ru'lun because of it's location.
It is located in the middle of Thronefast, Wilds End, and the Port of Ru'lun. It looks like a great place for mid level adventure and meeting new people. Many life long friendships could be formed here due to the location.
It would be a great place for an outpost to sell and buy goods and probably contains many valuable resources.
The fishing would be nice in the river.
There are probably large animals here and I would suspect Giants too.
Great place to spend a week.

I'd look around. See what NPC's do what, hail a few, see where things are, what armors I can buy when I can afford it- IF I can buy. Hopefully have enough wherewithal to buy food and drink to last another day, Ask around (NPC's) top see what to do next.
Deliver mail? (sounds easy enough)
