My wife is going there for 4 days. Unfortunately, I can't be with her because it was a surprise assignment. Any tips, trivia etc.

Her provided allowance for 4 days is just a little over US$1,000. Is that enough or just enough for bare survival? How much should one have in his/her pocket in local currency for convenience?

Her Hotel (and food), chartered car, plane are all provided for already.

Thanks in advance.
