Fix this by explaining to her how much money she can "save" buying diamonds while on the trip. This is also a reason for trip two. The diamonds on trip one cost a lot, but they pay off by your getting to go back!

I was thinking two trips would be better, just not sure if I should split up the dangerous game and get what plains game I can while doing the dangerous game or to do a plains game hunt and then pack all my dangerous game into one hunt. Still debating.
