It adds up, but not so quickly. RDP is "smart." The bandwidth requirements can vary from a few KBPS to ~100. What ends up happening is, if you need more bandwidth in this scenario you're going to need it in general - for downloading files, emails, etc.. Email, usually, takes about the same bandwidth. So, if Amazon is taking that burden, you should be OK.
