So my prediction from last month about my spending was correct. Since I've started keeping track of exactly how much I spend every month this is the most. So much that I actually spent more money than I earned. However my vacation was awesome and I regret nothing. One lesson that I can learn from this is to plan my vacation in more detail. One reason that I spend this much money is that I hadn't bough a return ticket and ended up paying a bit to much to get home.
