I'll be in Buenos Aires for Christmas and would like to go to Punta Del Este for 4 days over the New Year's Holiday. It appears that virtually all hotels are not showing any room available then. Apparently, from what I am reading online, they are all being held by travel agencies in Buenos Aires, so you have to book through them? If so, how do I go about finding these travel agencies and booking it now from North America? I assume when I arrive in BA on Dec. 20th that it will be impossible to find something at that point?
