I am still struggling with the idea of how much stuff to pack. I tend to be very simple and travel light so I'm afraid of under packing. Do you really drag all the toiletries, laundry soap etc with you?? I know it would be expensive in the park but the idea of shipping it also seems just as expensive and a waste of resources. I'm not bringing a car so its either ship ahead or purchase on arrival for me. I'm assuming that even if I don't get out of the park I will be able to find shampoe and deodorant? Some of you with more experience please give me some thoughts on this subject.
