Remember to pack extra storage for the stuff you buy... empty chip pages, tubes, etc. And remember not to pack this stuff in your suitcase but to carry it on the plane. Also, I expect the rooms have a safe in them, remember to use it if you don't carry everything around with you!!!

You may also want to consider buying one of these boxes for temporary storage of chips, especially good for a large quantity of traders. They are fantastic in that the chips don't move around. I'm pretty sure other people use them.
I don't know if this is the best price but you can see what it's like
