I’ve had a few people say that if I’m going all the way over there, I should go for longer than a week but I wouldn’t want to put you and Matt out. Besides, it might be hard for you to get more than a week off.
I think a full week would be enough. If I left home on Sunday and then flew out the following sunday or something like that. Then I’d have 6 or 7 days there and the days spent on the plane wouldn’t be wasted.
