I managed to spend 3000 US dollars on my month there -_- ... and I had a place to stay! When I went there I was all "no spared expense!" and did some expensive stuff and ate expensive food 8).
In any case, make sure you plan that out! If you have a travel agent, they may be able to help you chart out a plan. Otherwise, you might get a little overwhelmed by how much there is to do and end up inefficiently trying to go everything like me
